Question

Each marble bag sold by Ann's Marble Company contains 7 blue marbles for every 4 yellow marbles. If a bag has 24 yellow marbles, how many blue marbles does it contain?

Answer 1

This is quite simple, take 24 and divide it by four to get 6 now all you do is multiply 6 by 7 to get 42 so there are 42 blue marbles.
