Subtraction of Mass | Difference Between the Units of Mass

In subtraction of mass we will find out how to discover the
distinction in between the systems of mass or weight. While deducting we require to
follow that the systems of mass i.e., kg and gram are transformed into grams
prior to subtraction and after that follow the easy subtraction procedure.

We can deduct systems of mass like regular numbers.

We will find out 2 various approaches to resolve subtraction utilizing the basic system and smaller sized system of mass. Trainees can practice both the approaches.

( i) Subtracting systems with conversion into gram

( ii) Subtracting systems without conversion into gram

Worked-out examples on subtraction of mass:

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

Solution:

Method 1 ( with conversion
into gram):

We understand, 1 kg = 1000 grams

Now kg and g are transformed into grams prior to doing subtraction
and after that we require to follow the easy subtraction procedure.

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

Now amount,

2 5 7 6 5 g

– 1 1 4 6 0 g

1 4 3 0 5 g

= 14 kg
305 g

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

Method 2 ( without.
conversion into gram):

Here kg and g are set up in various columns and after that.
included like regular numbers.

Follow the actions:

( i) kg and g are set up in columns

( ii) 765 g – 460 g = 305 g

( iii) 25 kg – 11 kg = 14 kg

kg g
25 765

– 11 460

14 305

= 14 kg 305.
g

Therefore, distinction.
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

Solution:

Method 1 ( with conversion.
into gram):

We understand, 1 kg = 1000 grams

Now kg and g are transformed into grams prior to doing subtraction.
and after that we require to follow the easy subtraction procedure.

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

Now amount,

45225 g

– 24565 g
20660 g

= 20 kg 660 g

Therefore, 45 kg 225.
g – 24 kg 565 g = 20 kg 660 g

Method 2 ( without.
conversion into gram):

Here kg and g are set up in various columns and after that.
included like regular numbers.

Follow the actions:

( i) kg and g are set up in columns

( ii) 225 g < < 565 g, then 225 g – 565 g, so 1 kg from 45 kg is obtained and contributed to 225 g

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

1225 g – 565 g = 660 ml

( iii) 45 kg decrease into 44 kg

44 kg – 24 kg = 20 kg

kg g
45 225

– 24 565
20 660

= 20 kg 660.
g

Therefore, distinction.
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.

Solution:

Here kg and g are set up in various columns and after that.
included like regular numbers (without conversion into gram).

kg g
37 675

– 21 370
16 305

= 16 kg 305.
g

Therefore, distinction.
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:

Subtract 900 g from 1060 g.

1060 900 = 160

Write 160 under grams column.

Subtract kgs. 104 44 = 60 kg Write 60 under kgs column.

To deduct weights, compose the number of kg and gin different columns the deduct like regular numbers, beginning from.

5.

Subtract 22 kg 70 g from 46 kg 90 g.
Solution:

Subtract 682 kg 541 g from 325 kg 193 g.
