Answer:

7.25

1.38

Explanation:

a) For first addition

4.36 + 2.89

Start adding from the right side. Take the last number and add them together.

9+6 = 15.................. write 5 and keep 1

Bring forward the kept "1"

3+8 + 1 = 12............. write 2 and keep 1

Bring forward the kept "1"

4+2 + 1 = 7...............write 7

∴ 7.25

b) For second subtraction

6.8 - 5.42 = 1.38

Start from the right side of each number

0 - 2 requires that you borrow "1" from "8" now turning "0" to "10" and "8" to "7".

now, 10 - 2 = 8...........write 8

7 - 4 = 3.............write 3

6 - 5 = 1..............write 1

∴ 1.38
