Paco ate 25% of a 16-slice pizza and placed the rest in the fridge. Santos ate 25% of the leftovers. a) How many pieces were left? b) What percent of the original pizza remained?

Answer 1

25% percent is 1/4. 1/4 x 16 is equal to 4 slices of pizza. That leaves 12 pieces. We now need to take 1/4 of 12. 1/4 x 12=3

This means to find the number of remaining pieces, we need to subtract 4 and 3 from 16. 16-7=9 pieces remaining

To get the percentage of remaining pieces, divide. 9/16 which is 56.25%
