Please share what you have learnt from the two videos,
(i) decimal place value and
(ii) multiplying & dividing decimals by 10, 100, 1000,
on the padlet.]]> 2017-07-03 20:48:40 UTC https://padlet.com/limweekeng/61gnqma5u0zp/wish/177973338 Darrell darrellgjw https://padlet.com/limweekeng/61gnqma5u0zp/wish/178004166 What I learnt from the decimal place value video is that the decimal point is to separate the whole numbers and the decimal numbers and I learnt from the MR DL video is that you multiply and divide by the power of tens by how many zeros there are. ]]> 2017-07-04 06:46:51 UTC https://padlet.com/limweekeng/61gnqma5u0zp/wish/178004166 Yu Qi 🍣🍩🍬🍦🍰🍭🍪🍔🍟 https://padlet.com/limweekeng/61gnqma5u0zp/wish/178005441 When multiplying decimals, the decimal point will go to the right. If there are 2 zeros, then move the decimals 2 places to the right. Add zeros if needed.
When dividing decimals, the decimal point will go to the left.

Example : 0.952 x 100 = 95.2 Because the decimal point goes to the right 2 times as there are 2 zeros. Example : 19.4 * 10 = 1.94 " * is divided "

1. A decimal point is used to separate whole numbers from fractional amounts;
2. Decimals are like a full stop;
3.When multiplying a decimal by 10, let's say, 8.9, move the decimal to the right once, so now the number is 0.89.
4. Similar patterns are used when multiplying by 100 and 1000. Simply count the number of zeros in the number, then move the decimal point accordingly.
5.When you divide, it is the opposite. Instead of the right, move the decimal point to the left. The acronym MR DL (Multiply Right, Divide Left) can help you to remember.
6.Decimals are like fractions as they count parts of things.
7. To see how else fractions and decimals are similar, please click the link below]]> 2017-07-04 07:57:05 UTC https://padlet.com/limweekeng/61gnqma5u0zp/wish/178008986 Tan Bang Yi https://padlet.com/limweekeng/61gnqma5u0zp/wish/178026554 1.This is a decimal point: .
2.The decimal point is used to seperate whole numbers from fractions of 1.
3.When we multiply with decimals, we move the decimal point to the right depending on the amount of zeros.
Example:
3.65x10=?
Notice there is one zero in ten.Therefore, move the decimal point one step to the right.Your answer should be 36.5.
4.When we divide with decimals, we move the decimal point to the left depending on the amount of zeros again.
Example:
36.5*10=?
Since there is one zero in ten, we can move the decimal point one step to the left.Therefore, we can safely say that the answer is 3.65.
5.Decimals can also be converted to fractions.
Example:
0.75=3/4
0.5=1/2
To convert decimals to fractions, you will have to take note of the place value.Take 0.75 as an example.The last digit of this number is in the hundredths place.So, to convert to fraction, I take out the 'ths' from hundredths and will end up with the word hundred which is a place value.Now, I take the number 75 and use it as a numerator and hundred(100) as my denominator.I end up with a fraction like this.75/100.Lastly, I will simplify it and end up with 3/4.
6.Lastly, place value.
The first value after the decimal point is the tenth place:0.3
Next is the hundredth place:0.03
then it is the thousandth place:0.003
and so on.

1.A decimal point is somrthing thta seperate the decimal from a whole number. If thers isn't a whole number, you must write it as '0' Eg : 0.34
2. All decimals have a decimal point
3.When multiplying, the decimal point will move to the right. If it is multiplying by 10, which have one zero, the decimal point move 1 place to the right. If multiply by 100, which has two zero, the decimal point move to the right by two places and so on.
4. Dividing will be the same as multipling except that when dividing, the decimal point will move to the right.
5. Decimals were like fractions and they cuold be used with each other frequenty.(As in...）
Eg: 0.25= 25/100=1/4
6. Decimals also have plave value. The number right behind the decimal point is in the tenths place and the one right to it is on the hundredths place and so on.
Eg: 0.123 ( 1 is in the tenths place and 2 is in the hundredth place and 3 is in the thousands place ） There could even be millionths place.
7.Decimals and whole numbers if you add a decimal straight behinde it have a never end queue of 0 Eg: 3.5= 3.500000000000000
000000000 ..... which may help you in division.
8. Decimals could also be used in money, mass, length ,litres or miliitres, vvolume and many more.
Eg: 1.845kg= 1845g or so as it mutiplies by thousand （for mass and lilometres only)
9. the decimal poin looks like this:

I also learnt that decimals can be very useful.

Example:
5=5.125
Decimals can also be converted into fractions and percentage.
Example:
0.5= 1/2 0.5=1/2=50%
2. What I learnt from the multiplying and dividing decimals by 10, 100, 1000 is MR and DL. MR stands for Multiplying Right. It means that when you multiply the decimal, the decimal point moves towards the right. DL stands for Dividing Left. It means that when you divide the decimal, the decimal point moves towards the left.
Examples:
Multiply--> 0.52 multiply by 10=5.2
Divide--> 5.32 divide by 10=0.532]]> 2017-07-05 09:20:24 UTC https://padlet.com/limweekeng/61gnqma5u0zp/wish/178092086 chiang weiheng https://padlet.com/limweekeng/61gnqma5u0zp/wish/178096633 1.What i learnt from the decimal video is that the decimal point separate the whole numbers from decimals.
2.when multiplying the decimals ,the decimal point will move right but if dividing the decimals,the decimal point will move left.If u multiply by 10,the decimal point will move one step to the right.If u multiply by 100, the decimal point will move two steps to the right.If u multiply by 1000, the decimal point will move three steps to the right.If u are dividing by 10 the decimal point will move one step to the left but if u are dividing by 100,the decimal point will move two steps to the left.if u are dividing by 1000,the decimal point will move three steps to the left.]]> 2017-07-05 10:24:21 UTC https://padlet.com/limweekeng/61gnqma5u0zp/wish/178096633 Li Xin https://padlet.com/limweekeng/61gnqma5u0zp/wish/178098281 I learnt that decimal point have many uses , one of the uses is to seperate the whole numbers and the decimal numbers.
The second thing that i learnt was the left side of a decimal point are always whole number while the rihgt side are always decimal number.Somthing to add on is that when each time you move to the right side it would be 10 times smaller . And when it goes to to the left side it will become 10 times bigger.]]> 2017-07-05 10:44:01 UTC https://padlet.com/limweekeng/61gnqma5u0zp/wish/178098281 Wen Xuan :):):):) https://padlet.com/limweekeng/61gnqma5u0zp/wish/178100660 I learnt that the decimal point separates a whole number and a decimal number. When multiplying, we should move the decimal place to the right. If we are dividing, then move the decimal place to the left.
Okay......I'm done]]> 2017-07-05 11:28:47 UTC https://padlet.com/limweekeng/61gnqma5u0zp/wish/178100660 Bibloisca https://padlet.com/limweekeng/61gnqma5u0zp/wish/178103365 I learnt that when dividing a decimal, the decimal point will move to the right.And when multiplying decimals, the decimal point moves to the right.And decimals can be converted to a fraction.
K, bye]]> 2017-07-05 12:14:32 UTC https://padlet.com/limweekeng/61gnqma5u0zp/wish/178103365 Sun Quan https://padlet.com/limweekeng/61gnqma5u0zp/wish/178106123 I learnt that when adding a decimal point, it will separate the whole number and a decimal number. If we want to multiply the decimals: 0.69 x 10, it will be 6.9 as we need to move one decimal place to the right since we need to multiply 10. If we want to multiply the decimals: 0.69/10, it will be 0.069 as we need to move one decimal place to the left instead to the right since we need to divide by 10.]]> 2017-07-05 12:58:19 UTC https://padlet.com/limweekeng/61gnqma5u0zp/wish/178106123 Christal https://padlet.com/limweekeng/61gnqma5u0zp/wish/178108770 I learnt that a decimal point is used to separate the whole number and decimals. I also learnt that when multiplying a decimal, the decimal place will move to the right and vice versa.
Decimals can be expressed as fractions too. For example:
0.83 is equal to 83/100 and 199.08 is to 199 8/10.
An example of multiplying and dividing decimals are shown clearly below..(respectively)
0.1 x 12
= 0.1 x 2 x 10
= 0.2 x 10
= 2

1.5 / 30
=1.5 / 3 / 10
=0.5 / 10
=0.05
Decimals are extremely useful as it is used frequently in real life.
Byezzz!

2.Decimal places are just like regular number places,except that instead of using them to count GROUPS,we use them to count PARTS(or FRACTIONS)of things.

3.Just like the whole number places can go on forever to the left,counting bigger and bigger groups,the decimal number places an go on forever to the right,counting smaller and smaller parts(or fractions).

4.The decimal point separates the number places that are used for counting whole values,(which are on the left side of the decimal point)from the number places that are used to count fractional values(which are on the right side of the decimal point).

5.If there is no decimal digits, then we don't need to use the decimal point to separate them from whole number digits.

6.If a number has decimal digits, then we call it a "decimal number" and the decimal point helps us quickly recognize which digit is in the ones place.

7.each time we move yo the left, the new number place counts amounts that are ten times bigger than the previous place, so each time we move to the right, that place should count amount that are ten times smaller than the previous place.

8.The amount that is ten times smaller than one is called "one-tenth".

9. One tenth of a tenth is called 'one-hundredth'.

10.One-tenth of one-hundredth is called 'one-thousandth'.]]> 2017-07-20 08:39:30 UTC https://padlet.com/limweekeng/61gnqma5u0zp/wish/179113029 https://padlet.com/limweekeng/61gnqma5u0zp/wish/1244455581 erm uuuuuuuu]]> 2021-02-26 08:56:14 UTC https://padlet.com/limweekeng/61gnqma5u0zp/wish/1244455581 mariam 10180418 https://padlet.com/limweekeng/61gnqma5u0zp/wish/1829601640 -2(3.1)]]> 2021-10-20 07:16:28 UTC https://padlet.com/limweekeng/61gnqma5u0zp/wish/1829601640
