We can multiply the units of mass kg and g by a number like ordinary numbers.
1. Multiply 115 kg by 6.
Hence, 115 kg × 6 = 690 kg
2. Multiply 32 kg 126 g by 7.

Multiply the grams by 7.

126 × 7 = 882 g. Write 882 under g column.

Multiply the kilograms

32 × 7 = 224 kg

Write 224 under kg column.

Hence, 32 kg 126 g × 7 = 224 kg 882 g.
Alternative method:
When measurements are given as combination of two units, we can also first convert the bigger units to lower units and then multiply.

First convert 32 kg 162 g into gram and then multiply by 7.

32 kg 126 g = 32000 g + 126 g

= 32126 g

32126 × 7 = 224882 g

Convert 224882 g into kg

224882 g = 224000 + 882 g

= 224 kg + 882 g

= 224 kg 882 g
3. Multiply 19 kg 763 g by 5. Solution:
Hence 32 kg 126 g × 7 = 224 kg 882 g

First convert 19 kg 763 g into gram and then multiply by 5.

19 kg 763 g = 19000 g + 763 g

= 19763 g

19763 × 5 = 98815 g

Convert 98815 g into kg

98815 g = 98000 + 815 g

= 98 kg + 815 g

= 98 kg 815 g

Hence, 19 kg 763 g × 5 = 98 kg 815 g

In subtraction of mass we will learn how to find the difference between the units of mass or weight. While subtracting we need to follow that the units of mass i.e., kilogram and gram are converted into gramsbefore subtraction and then follow the simple subtraction process.

While adding we need to follow that the units of mass i.e., kilogram and gram are converted into gramsbefore addition and then follow the simple addition process. We can add two or more units of mass given in kilogram and grams like ordinary numbers. Always express grams as 3-digit numbers for example 3 g = 003 g

In subtraction of mass we will learn how to find the difference between the units of mass or weight. While subtracting we need to follow that the units of mass i.e., kilogram and gram are converted into grams before subtraction and then follow the simple subtraction process.

We can subtract units of mass like ordinary numbers.

We will learn two different methods to solve subtraction using the standard unit and smaller unit of mass. Students can practice both the methods.

(i) Subtracting units with conversion into gram

(ii) Subtracting units without conversion into gram

Worked-out examples on subtraction of mass:

1. Subtract 11 kg 460 g from 25 kg 765 g

We know, 1 kg = 1000 grams

Now kg and g are converted into grams before doing subtraction and then we need to follow the simple subtraction process.

11 kg 460 g = (11 × 1000) g + 460 g = 11000 g + 460 g = 11460 grams

25 kg 765 g = (25 × 1000) g + 765 g = 25000 g + 765 g = 25765 grams

Therefore, 25 kg 765 g - 11 kg 460 g = 11 kg 305 g

Here kg and g are arranged in different columns and then added like ordinary numbers.

(i) kg and g are arranged in columns

(ii) 765 g - 460 g = 305 g

(iii) 25 kg - 11 kg = 14 kg

Therefore, difference of 11 kg 460 g from 25 kg 765 g = 14 kg 305 g

2. Subtract 24 kg 565 g from 45 kg 225 g

We know, 1 kg = 1000 grams

Now kg and g are converted into grams before doing subtraction and then we need to follow the simple subtraction process.

24 kg 565 g = (24 × 1000) g + 565 g = 24000 g + 565 g = 24565 grams

45 kg 225 g = (45 × 1000) g + 225 g = 45000 g + 225 g = 45225 grams

Therefore, 45 kg 225 g - 24 kg 565 g = 20 kg 660 g

Here kg and g are arranged in different columns and then added like ordinary numbers.

(i) kg and g are arranged in columns

(ii) 225 g < 565 g, then 225 g - 565 g, so 1 kg from 45 kg is borrowed and added to 225 g

1 kg + 225 g = 1000 g + 225 g = 1225 g

1225 g - 565 g = 660 ml

Therefore, difference of 24 kg 565 g from 45 kg 225 g = 20 kg 660 g

3. Subtract 21 kg 370 g from 37 kg 675 g without conversion into gram.

Here kg and g are arranged in different columns and then added like ordinary numbers (without conversion into gram).

Therefore, difference of 21 kg 370 g from 37 kg 675 g = 16 kg 305 g

4. Subtract 44 kg 900 g from 105 kg 60 g.
Solution:

Arrange the numbers vertically.

First, subtract the grams.

1060 - 900 = 160

Write 160 under grams column.

Subtract kilograms. 104 - 44 = 60 kg

Write 60 under kilograms column.

The above problems on subtraction of mass will help the students to practice the worksheet on subtracting the different units with conversion or without conversion.

Now sum,

25765 g

-   11460 g
14305 g
= 14 kg 305 g

Therefore, 25 kg 765 g - 11 kg 460 g = 11 kg 305 g

Mass is used to measure the weight of an object. For example, you are measuring the mass of your body when you step on to a scale. In the metric system of measurement, the most common units of mass are the gram and kilogram

The basic SI unit for mass is the kilogram (kg), but smaller masses may be measured in grams (g). To measure mass, you would use a balance. In the lab, mass may be measured with a triple beam balance or an electronic balance, but the old-fashioned balance pictured below may give you a better idea of what mass is.4 Aug 2021

How to convert mass - To find weight when you already know the mass, use the formula weight = mass times gravitational acceleration. Remember that on the surface of the earth, gravitational acceleration is always 9.8 m/s^2, so simply plug in the mass and multiply it by 9.8 to get the weight in newtons.
