I am making oatmeal cookies and one batch calls for 2 3/4 cups of flour. If I am going to make 4 batches, how many cups of flour will I need?

The easiest way to figure this out is by multiplying improper fractions. So, the first step will be turning both into improper fractions:

2 3/4 = 11/4

4 = 4/1

Then, multiply the numerators and denominators.

11 x 4 = 44

1 x 4 = 4

This gives you 44/4. Lastly, simplify your fraction with basic division. You're answer should be 11.

I would say 11 cups of flour is needed for 4 batches. i am sorry if i am wrong.
