Hi girls! We're missing you all and hoping you're all keeping safe. We're going to use Padlet for some maths work. It's simple really! All you girls need to do is watch content that we add to this and then try out the questions we set in a copy at home. There is a little heart symbol after every post- Could you please only click this if you have understood what we have put up? You can ask questions about anything you are not sure of in the comments box but you must write your name beside it. We will get back to you on any questions you have.
Thanks!
Ms. Norton & Ms. Kenny

Look over the following table. You should be able to recognise the following ways of expressing the same amount. Be sure to test yourself and learn this table! It will really help if you know this well.

1          1.0        100%

½         0.5          50%

⅓         0.33        33 ⅓ % or 33.3 %

⅔         0.66        66  ⅔ %

¼         0.25        25%

¾         0.75        75%

⅕         0.2          20%

⅖         0.4          40%

⅗         0.6          60%

⅘         0.8          80%

⅛         0.125      12 ½ % or 12.5 %

⅜         0.375       37 ½ % or 37.5 %

⅝         0.625       62 ½ % or 62.5 %

⅞         0.875       87.5  % or 87.5 %

1/10         0.1           10 %

3/10          0.3           30 %

7/10          0.7           70%

1/100        0.01            1%

13/100      0.13          13%

You should be able to spot that there was no need to put in 2/8 in the table as it is an equivalent fraction of ¼ so 2/8 = 0.25 = 25%.

1 (a) Can you work out how to express 4/8 and 6/8 as decimals and percentages? Try it out!

You also probably worked out that 5/10 is also 1/2 in its lowest or simplest terms and it can be written as 50% or 0.5.

1(b) How would you write 4/10  or 6/10 or 8/10  in their lowest terms and as decimals or  percentages?

Let us know how you got on with these!

If it suits everyone we might try to have an online quiz next week on the decimals/fractions/percentages table. Hope that's ok :-)

Well done to all of you who got started on your maths yesterday! We have changed the layout of this Padlet to make it easier to follow. Just scroll down and try each box separately. Don't forget to write your name beside a comment you make.

Take a quick look back at your equivalence table from yesterday which showed the relationship between fractions, decimals and percentages and see how many you know off by heart.

We are going to continue by changing decimals to percentages today.

So first of all, take a look at these examples;

Examples

1.0 = 100%

0.1 =   10%

0.01=     1%

Now try these questions and convert them to percentages:

1)0.5 = ____    2) 0.2 = _____
3) 0.04 = _______   4) 0.17 = _____

Hopefully you all found those 4 questions quite easy. If you have any questions please add your comment to the box and don't create a new one. When you're ready, move onto the next box by scrolling down.

Now let’s try changing percentages to fractions and decimals. Remember, percentage means per hundred. You have to begin by rewriting the percentage as a fraction over a hundred. For example 30% would be written as 30/100.
After that, find the largest number that will divide into the numerator and the denominator. Sometimes you might have to further divide if you are asked to write the fraction in its lowest terms/Simplify.Here are 3 examples.
Example A.

Change a percentage to a fraction;

60% = 60/100 can be divided by 10/10 = 6/10

6/10 can be simplified when divided by 2/2 to  3/5

So 60% = 3/5

Some of you will have spotted that 60/100 could have been divided by 20/20 to give the same answer.

Example B

Change 15% to a fraction

15% = 15 /100

15 /100 can be divided by 5/5 to give an answer of 3/20

Example C

Change 31% to a fraction

31/100 is already in its lowest terms so the answer is 31/100

Now give these a go:
1) 25%  = ______      2) 24% = _____   3)  45 %= ____         4) 5% = ______

5) 37%  = ______     6) 16% =_____

Part 3: If you found those questions easy, you might like to follow these examples and try a few more challenging questions.

Example D

Convert   33 1/3 % to a fraction.

You must begin by getting rid of the fraction which you must multiply by a member of the family of one.

So multiply   33 1/3/100  by 3/3 to give an answer of 100/300.

Now as you know 100/300 can then be divided by 100/100 to give an answer of ⅓

Example E

Convert 12 ½ % to a fraction .

Step 1: Multiply by 2/2 to get rid of the fraction part.

12 1/2 /100  x 2 /2 =  25/200

25/200 can be divided by 25/25 =  1/8

Try these questions;

1) 37 1/2% = ________
2) 11 1/2%  ___________
3) 83 ⅓ %______

Well done everyone! We know this online stuff isn't easy but you're doing great!

Hi everyone! We are delighted you are working on your maths and please just ask if you need more help. We really want to help you, but we need you to tell us which questions you are finding difficult.

Begin with some revision. Try to convert the following fractions into decimals and percentages:
1) 1/1
2) 1/2
3) 1/5
4) 7/8
5) 3/10
How were they?

# data[].attributes.body
Now we are going to look at expressing numbers as a percentage of each other. Do you remember doing tests and then changing your result into a percentage? For example, if you got 15/20 in a spelling test, you could change that into a percentage by multiplying 15/20 by 5/5 to discover that you got 75% of the spellings correct. Perhaps you had already known that 15/20 is ¾ in its lowest terms and worked out the percentage because you knew that ¾ is 75 %.

# data[].attributes.body
Here is another method for writing numbers as a percentage of each other;

If it rained for 27 days in April, what percentage of the month was the weather wet?

(30 days in April)

You put 27 over 30 and then you must multiply by 100/1 .

(You could cancel out some of the zeroes by dividing by 10/10)

27/30  x 100/1  = 2700/30 = 90/1 =  90%

Now try that method to work out the percentage of sunny days in June, if there were 18 sunny days out of 30 days.

Did you get an answer of 60%?

18/30  x 100/1 = 1800/30 = 60/1 = 60%

# data[].attributes.body
Now write each of the following as percentages;

a. It snowed for 7 of the 28 days in February.

b. There was a heatwave for 21 of the 30 days in September.

c. November had 9 cold days out of 30 days.

d. June had temperatures above 18 degrees on 24 days

Well done everyone! If you’re up for a challenge then try the following questions and let us know how you got on:

1) Sonia had €85. She spent 60% of her money on a dress. How much had she left?

2) 87.5 % of Millie’s money is €54.60. How much has she altogether?

Hi girls! It would be great if you could test yourself on your tables as we do in school with the Ballard tests. Click the image below and start a timer. Afterwards you could use a calculator to correct your work. Try to test your tables at least once a week. Let me know your quickest times and scores below if you'd like :-)
