1.	Using brackets write three pairs of numbers whose:i. Sum is 9ii. difference is 9iii. multiplication is 16 andiv. division is 16.
Answer» i. Sum is 9 5 + 4 = 9, 7 + 2 = 9, 8 + 1 = 9 ii. difference is 9 12 – 3 = 9, 11 – 2 = 9, 10 – 1 = 9 iii. multiplication is 16 and 4 x 4 = 16, 8 x 2 = 16, 16 x 1 = 16 iv. division is 16. 32 ÷ 2 = 16, 48 ÷ 3 = 16, 64 ÷ 4 = 16,

Using brackets write three pairs of numbers whose:i. Sum is 9ii. difference is 9iii. multiplication is 16 andiv. division is 16.

Answer»

i. Sum is 9

5 + 4 = 9,

7 + 2 = 9,

8 + 1 = 9

ii. difference is 9

12 – 3 = 9,

11 – 2 = 9,

10 – 1 = 9

iii. multiplication is 16 and

4 x 4 = 16,

8 x 2 = 16,

16 x 1 = 16

iv. division is 16.

32 ÷ 2 = 16,

48 ÷ 3 = 16,

64 ÷ 4 = 16,
