Harvey collects marbles. He has 112 marbles. Each tray holds an equal number of marbles. If he uses 7 trays to hold all of the marbles, how many marbles will he display on 3 trays?
*please show work too I would really appreciate it thanks*
Harvey has 112 marbles and 7 trays that hold an equal number of marbles each. To find the number of marbles in 3 trays, you need to find the number of marbles that each tray holds. In order to do this, you need to divide:
112/7 = 16 (number of marbles divided by the number of trays)
This gives you 16, which is the number of marbles in 1 tray. To find the number of marbles in 3 trays, you need to multiply the number of marbles in each tray times the number of trays:
