Question

Caitlin is making oatmeal cookies

She wants to make 1 1/2 batches
Each batch of cookies requires 2 1/2 cups of oatmeal
She has 3 1/4 cups of oatmeal
How many more cups of oatmeal does Caitlin need?

Answer 1

Answer: She needs 1/2 a cup of oatmeal

Explanation:

step 1. turn the 2 1/2 into a decimal to get 2.5

step 2. divide the decimal in half to get 1.25

step 3. add 2.5 + 1.25 = 3.75

step 4. take that answer and subtract it by how much oatmeal you have (3.25) to get 0.5 this means that you need half a cup of oatmeal to make 1 1/2 batches of oatmeal cookies
