Question

You know that 125 is a composite number because it is divisible by ___. A. 2 B. 3 C. 5 D. 7

Answer 1

Well, since the last number in 125 is 5, it can't be divided by 2.

125 divided by 3 is 41.6 repeated, which isn't the correct answer.

125 divided by 7 is 17.85714285714286, which isn't a correct answer either.

So.. The answer is  C. 5

Answer 2

The answer is C. 5

This is the answer because

125 / 2 = 62.5

125 / 3 = 41.6_

125 / 5 = 25

125 / 7 = 17.86

As you can see 5 is the only number it can be divisible by.

Hope that helps!!
