Shelby needs 4/8 of a cup of oatmeal for each batch of cookies. If she wants to bake 7 batches, how much oatmeal will she need?

3 and 1/2 cups

Step-by-step explanation:

Here you are going to multiple the number of cups by the number of batches to get your total. That is going to be 4/8 times 7 (but putting it into terms of a fractions as 7/1 is better.) So 4/8 times 7/1. Multiply the numerators = 28 Multiply the denominators= 8

28/8=

3.5 or 3 and 1/2

b) well because you get well

i belive those are the ones that are under 90 degreese.
