What are the first five multiples of 9

Answers

Answer: 0, 9, 18, 27, and 36

Step-by-step explanation: To find the first five multiples of 9, multiply 9 by the first 5 whole numbers {0, 1, 2, 3, 4}.

0 x 9 = 0

1 x 9 = 9

2 x 9 = 18

3 x 9 = 27

4 x 9 = 36

So the first five multiples of 9 are 0, 9, 18, 27, and 36.
9*1 = 9
9*2 = 18
9*3 = 27
9*4 = 36
9*5 = 45

The first five multiples of 9 are 9, 18, 27, 36, 45~
