Answer 1

Answer:

(4) 1000

(5) 3/8

Step-by-step explanation:

(4) Let's assume the number x should be added to - 10 to get 990.

- 10 + x = 990

x = 990 + 10

x = 1000

Hence, the number 1000 should be added to - 10 to get 990

(5) Let's assume the number y should be subtracted from 3/4 to get 3/8.

3/4 - y = 3/8

- y = 3/8 - 3/4

- y = 3/8 - 6/8

- y = - 3/8

x = 3/8
