Question

Raina must choose a number between 55 and 101 that is a multiple of 2,3 and 9. Write all the numbers that she could choose. If there is more than one number, separate them with commas.

Answer 1

72,90

Explanation:

Since 9 is the biggest number so list multiples of 9 between 55- 101 range.

Which are 63, 72, 81, 90, 99. Any number that is a multiple of 9 is a multiple of 3 because 3x 3 = 9. 9 is a multiple of 3.

Any even number is a multiple of 2.

Only 72 and 90 are even numbers.

So 72 and 90 are numbers divisible by 2, 3, 9.
