recipe contains 3/4 cup of molasses. this recipe serves 8 people. if she makes the one that serves 12 people

Question

and the ratio of molasses to people is the smae how much molasses will she need

Answer 1

This can be solved using a proportion. Let m = the amount of molasses used to serve 12 people.

 

Then:

 

m/(3/4) = 12/8.

 

Solve for m by multiplying both sides by 3/4:

 

m = 12/8 · 3/4 = 36/32 = 9/8 = 1 1/8 cups of molasses are required.
