E 14. Jillian picks some grapefruit . She places all the grapefruits that weigh exactly 1/2 pound into a bag. The total weight of the bag is 6 1/2 pounds. How many grapefruits are in the bag? Show your work and explain why you chose the operation you did.

Answer 1

Answer:

There are 13 grapefruits in the bag

Explanations:

Jillian placed all the grapefruits that weigh exactly 1/2 pounds into a bag. This means that:

Weight of 1 grapefruit = 1/2 pounds = 0.5 pounds

Let the number of grapefruits = n

The total weight of the bag (I.e all the grapefruits) = 6 1/2 = 6.5 pounds

Total weight of the bag = Number of grapefruits x Weight of 1 grapefruit

6.5 = n x 0.5

0.5n = 6.5

n = 6.5 / 0.5

n = 13

There are 13 grapefruits in the bag
