Lucy and JoJo need to make 140 cupcakes for the school dance, .
Lucy made 3/5of the cupcakes
• How many cupcakes does JoJo need to make?

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

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
