Question

Sarah has 150 marbles. Of the marbles, 2/5 are blue, 3/10 are clear, and the rest are green. What is the ratio of blue marbles to clear marbles to Green marbles in simplest form?

Answer 1

4 : 3 : 3

Explanation:

2/5 of 150 = 300/5 or 60; therefore, there are 60 blue marbles

3/10 of 150 = 450/10 or 45; therefore, there are 45 clear marbles

150 - (60 + 45) = number of green marbles; there are 45 green marbles

Blue : Clear : Green ratio is 60 : 45 : 45 or 4 : 3 : 3
