Dustin and Kate each made a bowl of punch. Kate used 3 3/4 times as much lemonade as Dustin did. If Dustin used 5 cups of lemonade, how many cups of lemonade did Kate use?


To find how many cups of lemonade Kate used, you multiply the amount Dustin used by 3 ¾.

Dustin used 5 cups of lemonade, so:

\[
\text{Kate's lemonade} = 5 \times 3\frac{3}{4}
\]

First, convert the mixed number \(3\frac{3}{4}\) into an improper fraction:

\[
3\frac{3}{4} = \frac{15}{4}
\]

Now, multiply:

\[
5 \times \frac{15}{4} = \frac{5 \times 15}{4} = \frac{75}{4} = 18\frac{3}{4}
\]

So, Kate used \(18\frac{3}{4}\) cups of lemonade.

### Answer:
Kate used \(18\frac{3}{4}\) cups of lemonade.
