Harvey collects rare marbles. He has 112 marbles in his collection. Each tray holds and equal number of marbles. If he uses 7 trays to hold all of the marbles, how many marbles will he display on 3 trays?

Three trays will hold 48 marbles

Step-by-step explanation:

Harvey collects rare marbles. He has 112 marbles in his collection.

This means the total number of marbles in his collection is 112. The marbles are held in trays. Each tray holds an equal number of marbles.

If he uses 7 trays to hold all of the marbles, this means 7 trays are used to hold 112 marbles. Since each tray holds the equal number of marbles,

The 7 trays will hold 112/7 = 16 marbles each.

Three trays will hold 16*3 = 48 marbles
