C. 60
D. 75

PLS ANSWER ASAP!!! ILL MAKE U BRAINLIEST♡

Explanation:

Since 300 is a multiple of some number, this means that mystery number is a factor of 300.

So for instance, she could have picked 60 since 60*5 = 300. Or she could have picked 50 because 50*6 = 300.

To find out if you have a factor or not, divide the 300 over each answer choice. If you get a whole number, then it is a factor.

Choices B through D lead to whole number results, which shows that the numbers 50, 60 and 75 are factors of 300. Flipping things around, this means that 300 is a multiple of 50, 60, and 75.

Only 45 is the one that isn't a factor of 300, which means that 300 is not a multiple of 45.

Another way to see this is to list out the multiples of 45

and we don't land on 300. The closest we get is 315.

In contrast, let's list out the multiples of 50

The value 300 is in the list, allowing us to cross off choice B. Choices C and D are similar.
