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

3:5

3 to 5

 3
-----
 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.
