Q:

First four multiples of 9?

Answer

A multiple of a number is the number multiplied by an integer.

The first four multiples of 9 are given by multiying the first 4 integers with number 9.

That is,

9 x 1 = 9

9 x 2 = 18

9 x 3 = 27

9 x 4 = 36

Hence, first four multiples of 9 are 9, 18, 27, 36.
