Question

3/4 cup of oatmeal is required to make a batch of Oatmeal cookies. Ellen is making 4 1/2 (four and a half) batches of cookies. How many cups of oatmeal will she need​

Answer 1

Answer:

6

Step-by-step explanation:

4(1/2) = 9/2         [Mixed to improper conversion]

9/2 = 18/4

for 3/4 cup of oatmeal we get 1 batch of Oatmeal cookies

for 18/4 let it be x batch of Oatmeal cookies we get

cups directly proportional to batches therefore

$\frac{3/4}{18/4}$ = $\frac{1}{x}$  

3/18 = 1/x

1/6 = 1/x

x = 6

so she will get 6 batches of oatmeal cookies
