If the ratio of blue marbles to red marbles in a bag is 5:10 and you have 75 marbles altogether. How many blue marbles do you have?

• 25

• 50

• 60

• 30

Answer explanation

If the ratio of blue marbles to red marbles in a bag is 5:10 and you have 75 marbles altogether. How many blue marbles do you have?

5 + 10 =15

15 parts = 75 so 75 divided by 15 =1 part, 1 part = 5

5 x 5 = 25 so there are 25 blue marbles

10 x 5 = 50 so there are 50 red marbles
