Question

Darren and Latisha are decorating cupcakes for a bake sale. They need to decorate 100 cupcakes. Each of them has decorated 40% of the cupcakes. What percentage of cupcakes do they have left to decorate?

Answer 1

Since they have both decorated 40%, they have decorated a total of 80% of the cupcakes.

They only need to decorate 20% of the cupcakes left.

Answer 2

Now they have left to decorate 20% cupcakes.

Explanation:

Darren and Latisha are decorating cupcakes for a bake sale.

They need to decorate 100 cupcakes.

Each of them has decorated 40% of the cupcakes = 40% + 40% = 80%

Both of them has decorated 80% of the cupcakes.

80% of 100 cupcakes = 80 cupcakes

Now they have left to decorate 100 - 80 = 20

Now they have left to decorate 20% cupcakes.
