Question

How do you set this problem up to solve and how do you solve this?

Ellen has four types of marbles, 120 marbles of each type. She trades two-fifths of the first type, three-eights of the second type, five-sixths of the third type, and three-quarters of the fourth type. Of the original 480 marbles, how many does Ellen trade?

Answer 1

2/5 * 120 = 240/5 = 48

3/8 * 120 = 360/8 = 45

Do the same for the other two types. Then add the answers together.
