Question

A bag contains 104 balls .

The ratio of red to blue to yellow balls is 1 : 8 : 4
Find how many red, blue and yellow balls there are .

Answer 1

Red = 8, Blue = 64, Yellow = 32

Explanation:

Using the the ratio, make an equation.

1x + 8x + 4x = 104

Simplify the left side

13x = 104

Divide both sides by 13

13x/13 = 104/13

x = 8

Now solve for each color

Red

1x

1(8) = 8

Blue

8x

8(8) = 64

Yellow

4x

4(8) = 32
