Answer 1

Answer:

answer of 10

Step-by-step explanation:

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

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

Method 2 (without conversion into gram):

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

Follow the steps:

(i) kg and g are arranged 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, difference of 11 kg 460 g from 25 kg 765 g = 14 kg 305 g
