Question

Write an expression for the number of scoops Zack needs to fill both feeders. (Each bird feeder holds 2 and 1/4 cups) (each scoop holds 1/4 cups)

Answer 1

Zack needs 18 scoops to fill both bird feeders, calculated by doubling the capacity of one feeder which is 2 and 1/4 cups, and then dividing the total capacity by the size of one scoop which is 1/4 cup.

Step-by-step explanation:

To calculate the number of scoops Zack needs to fill both bird feeders, we first need to find the total capacity of the feeders in cups. Since each feeder holds 2 and 1/4 cups, and there are two feeders, we need to calculate:

• 2 and 1/4 cups + 2 and 1/4 cups = 4 and 1/2 cups (total capacity needed for both feeders).

Now, since each scoop holds 1/4 cup, we can determine the number of scoops by dividing the total capacity needed by the capacity of one scoop:

• 4 and 1/2 cups ÷ 1/4 cup/scoop = 18 scoops.

Therefore, Zack needs 18 scoops to fill both bird feeders.
