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.
