A bag of marbles has pink, blue, and green marbles at ratio of pink:blue:green=4:2:1. There are 72 blue marbles in a bag. how many pink marbles are in the bag?

There are 144 pink marbles in the bag.

Step-by-step explanation:

The ratio 4:2:1 means that for every 2 blue marbles there are 4 pink and 1 green.

This said,

We have 72 blue marbles in the bag, the number of pink marbles is exactly twice the amount (4 : 2), so 72 (2) = 144

Another way to find the answer is looking for the half of the blue marbles which is 36 and then multiply it by 4 (pink marbles) and your answer will be also 144.

Hope this help!
