Answer 1

Rebecca's soup recipe calls for 3/4 cup milk.

She needs 3 times as much milk to make a triple batch of soup.

How many cups of milk does Rebecca need?

Since 1 batch of soup required 3/4 cup of milk then 3 batches of soup will require 3 times of 3/4 cup of milk.

$\begin{gathered} 3\times\frac{3}{4}=\frac{3\times3}{4}=\frac{9}{4} \\ or \\ \frac{3}{4}+\frac{3}{4}+\frac{3}{4}=\frac{3+3+3}{4}=\frac{9}{4} \end{gathered}$

Which can be also be written as

$\frac{9}{4}=2\frac{1}{4}$

Therefore, she needs 9/4 cups of milk or 2 and one-fourth cups of milk.
