A multiple is a number that can be obtained by multiplying a number by another number.

(a) 5

First five multiplies of 5 are;

1 × 5 = 5

2 × 5 = 10

3 × 5 = 15

4 × 5 = 20

5 × 5 = 25

So,

The first five multiplies are 5, 10, 15, 20 and 25.

(b) 8

1 × 8 = 8

2 × 8 = 16

3 × 8 = 24

4 × 8 = 32

5 × 8 = 40

So,

The first five multiplies of 8 are,

8, 16, 24, 32 and 40.

(c) 9

1 × 9 = 9

2 × 9 = 18

3 × 9 = 27

4 × 9 = 36

5 × 9 = 45

So,

First five multiplies are 9, 18, 27, 36 and 45.
