Answer:
The answer is 2 cakes.
Step-by-step explanation:
What we know:
-Each cake requires 2 1/2 cups of sugar.
-Sheila has 7 1/3 cups of sugar.
What we need to know:
-How many cakes can Sheila make with 7 1/3 cups of sugar.
Remember:
-You must make a whole cake.
Show your work:
-I am going to convert the fraction into a decimal.
-2 1/2=2.5 and 7 1/3=7.3
-2 cakes will require 5 cups of sugar and you will remain with 2.3 cups of sugar.
-You <em>cannot </em>use 2.3 cups of sugar to make a cake. It must be in full.
