Question

Mr. Staufer bought a 10-pound bag of sugar to make cookies. There are 3 cups of sugar to apound. He needs 1 1/3 cup of sugar per batch of cookies. How many batches of cookies can Mr.Staufer make?

Answer 1

We have a total of:

`10\cdot3=30`

30 cups of sugar in the 10 pound bag. If we need 1 1/3 cups per batch we can make a total of:

`(30)/(1(1)/(3))=(30)/((4)/(3))=((30)/(1))/((4)/(3))=(90)/(4)=22.5`

22.5 batches of coockies.
