Jasmine and 3 of her friends are tasting wedding cakes. Each person ate three-fifths of a cake. What is the total amount of cake that Jasmine and her 3 friends ate?
First, calculate the amount of cake each person ate:
3/5 cake/person * 4 people = 12/5 cakes
Now, calculate the total amount of cake that Jasmine and her 3 friends ate:
12/5 cakes/person * 4 people = 48/5 cakes
Therefore, Jasmine and her 3 friends ate a total of 48/5 or 9.6 cakes.
