A pancake recipe asks for one and one half times as much milk as flour. If three and one half cups of milk is used, what quantity of flour would then be needed, according to the recipe?

Answer 1

pancakes require 1.5 cups of milk and 1 cup of flour, or a ratio of 1.5:1 or a fraction of

(1.5) / (1)

If you have 3.5 cups of milk you need x cups of flour

Set up a ratio of 1.5 / 1 = 3.5 / x (1.5 divided by 1 equals 3.5 divided by x)

Cross multiply one numerator by the other denominator, and then the other way, too.

1.5x = 3.5

divide both sides by 1.5

x = 35/15 = 2 1/3 cups
