Carol has 4 cups of candy corn to decorate cookie. she wants to put 1 /12 of a cup of candy on each cookie. how many cookies can he make

What we need to find is how many cookies we can make that have 1/12 cups of candy using 4 cups of candy corn.

What we know: 
4 cups of candy
1/12 cup per cookie

We need to divide 4 cups of candy corn into groups of 1/12.

4/(1/12)   
4/1 x 12/1=4x12=48

So, we have 48 groups of 1/12 cups of candy corn that means we can make 48 cookies each containing 1/12 cup of candy corn.
