Each marble bag sold by Melissa's Marble Company contains 3 orange marbles for every 5 blue marbles. If a bag has 24 orange marbles, how many blue marbles does it contain?

5

First we will divide to see who many sets of orange there are in the bag.

24 ÷ 3 = 8

Since there are 8 sets of orange we will multiply 8 by 5 since for every 3 orange marbles there are 5 blue marbles.

8 × 5 = 40

SO, a bag contains 24 orange marbles and 40 blue marbles.

Hope i helped ya!

3/5=24/x. cross multiply, you get 120=3x. divide by 3, x = **40**
