Question

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

Answer 1

Let x = amount of flour

 

x =  amount of milk / 2.5

 

x =(3 1/3) / 2.5

 

change both to improper fractions

 

x = 10/3 / (5/2)

 

Now invert and mutiply

 

x = 10/3 * 2/5

 

x = 4/3 

 

Hope this helps
