Solved Multiples of 18 Examples

Find if 144 is a multiple of 18:

Divide 144 by 18:

144 ÷ 18 = 8
144 ÷ 18 = 8 (a whole number, no remainder)

Hence, 144 is a multiple of 18.

Is 200 a multiple of 18?

Divide 200 by 18:

200 ÷ 18 = 11.11
200 ÷ 18 = 11.11 (not a whole number)

Therefore, 200 is not a multiple of 18.
