Question

In a crayon box there are 5 dark colors for every 8 light colors. If there are 20 dark colors, how many light colors are there?

Answer 1

If we write this as a ratio then it would be 5:8. Now since there are 20 dark colors and also 5, what do 5 and 20 have in common... 5 times 4 is 20 so since we multiplied by 4 on dark colors do the same  to the light colors so 8 times 4 = 32. So the answer is 32 light colors

Answer 2

5x4=20 so 8x4=32 32 light colors in the box
