Mrs. Smith is having a birthday party for her grandson. 75 people will be there. If 3/5 of them are bringing desserts and 1/5 are bringing candy, and the rest are bringing punch, how many are bringing punch?
If one fifth is bringing candy and three fifths is bringing dessert than that already four fifths of the people who aren't bringing punch so one fifth of the people are bringing punch so one fifth of 75 is equal to 15
