Question

A pancake recipe requires one and one quarter cups of milk to one cup of flour. If one and two thirds cups of milk is used, what quantity of flour will be needed, according to the recipe?

Answer 1

4/3 cups of flour or 1 and 1/3 cups of flour

Explanation:

Using the proportions, you can cross multiply and find the ratio of cups of milk to cups of flour. x = the amount of flour needed

`(5/4)/(1) = (5/3)/(x)` -equation

5/4x = 5/3 (1)- cross multiply

`(5/4x)/(5/4) = (5/3)/(5/4)` - isolate the x

x= 4/3 or 1 and 1/3
