Question

Franks teacher put red and blue marbles into a bag. She told class that exactly 3/5 of the marbles are red. She then asked how many total marbles could be in the bag.

Answer 1

Frank is incorrect

Explanation:

Frank is incorrect because since the denominator of the ratio is 5 that means in order to get the total amount of marbles inside of the bag the total amount has to be a multiple of 5. And in the three numbers that are given to us there is only one multiple of 5 which is 20 . so, that is why Frank is incorrect.
