Ms. Smith purchased ½ of a pound of grapes. She would like to make 112pound portions for this week’s snacks. How many portions w
Elodia [21]

Step-by-step explanation:

There is no enough information to determine how many portions she will be able to make.

We need to know how many pounds of grapes will she needs to make a particular pounds portions for the snacks.

For example, if she needs 2 pounds of grapes to make 5 pounds portion for the snacks, and she purchase ½ pounds of grapes, we can determine how many pounds of portions for the snacks she will be able to make with this information.

Using a simple ratio

2:5 = ½:x

2/5 = ½/x

Multiplying both sides by x

(2/5)x = 1/2

Multiplying both sides by 5/2

x = (1/2)×(5/2)

x = 5/4

x = 1¼ pounds

Meaning she will be able to make 1¼ pounds of portion for snacks with ½ pounds of grapes.
