Question

Daniel is making cupcakes for a dinner party. He already used
$\frac{1}{4}$th of a cup of whipped cream and wants to use the remaining cream for the cupcakes. If he wants to put $\frac{1}{6}$th of a cup of whipped cream on each cupcake, how many cupcakes can he make?

• A. 4
• B. 0
• C. 6
• D. 24

Answer 1

The correct option is A 4

Amount of whipped cream already used = $\frac{1}{4}$ of a cup
Amount of whipped cream left = $1-\frac{1}{4}=\frac{4}{4}-\frac{1}{4}=\frac{3}{4}$ of a cup
Quantity of whipped cream required for one cupcake = $\frac{1}{6}$ of a cup
Total number of cupcakes Daniel can make = amount of whipped cream left $÷$ quantity of whipped cream required for one cupcake
$=\frac{3}{4}÷\frac{1}{6}$
Using the keep, change, and flip rule, we get
$=\frac{3}{4}\times \frac{6}{1}=\frac{18}{4}=4\frac{2}{4}$
So, Daniel can make 4 cupcakes using the whipped cream left.
