Lucy and JoJo need to make 140 cupcakes for the school dance,
Pepsi [2]

Answer:

56 cupcakes

Step-by-step explanation:

First, I convert 3/5 to a percent because I prefer to work with percents:

3/5 = 0.6 = 60%

Then, subtract 60% from 100% for the percent of the total cupcakes that JoJo needs to make:

100 - 60 = 40%

Finally, multiply the total cupcakes by the percent as a decimal:

140 × 0.4 = 56
