Answer:

Worked-out examples on addition of mass:

1. Add 7 kg 350 g and 2 kg 150 g

Solution:

Method 1 (with conversion into gram):

We know, 1 kg = 1000 grams

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

7 kg 350 g = (7 × 1000) g + 350 g = 7000 g + 350 g = 7350 grams

2 kg 150 g = (2 × 1000) g + 150 g = 2000 g + 150 g = 2150 grams

Now sum,

1

7350 g

+ 2150 g

9500 g

= 9 kg 500 g

Therefore, 7 kg 350 g + 2 kg 150 g = 9 kg 500 g

Method 2 (without conversion into gram):

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

kg g

1

7 350

+ 2 150

9 500

= 9 kg 500 g

The answer is
