Question

cookie recipe calls for 1 1/3 cups of flour to make 36 cookies. How much flour is needed to make 27 cookies

Answer 1

Set up a proportion

 

1 1/3 = 4/3

 

so we have 36/(4/3) = 27/x , where x = the number of cups of flour needed to make 27 cookies

 

36x = 4/3 (27)

 

36x = 36

 

x = 1

 

One cup of flour is needed to make 27 cookies
