Activity

Priscilla’s grandmother’s fruit salad recipe calls for one part apple, one part orange, four parts strawberry, two parts cherry, and three parts grape. Priscilla uses the same measuring cup to measure all of the fruit, so one part is equal to one cup of diced fruit. In this exercise, you will compare the quantities in the recipe to understand ratios better.

Part A
Write a sentence comparing the quantity of apples with the quantity of grapes.

Part B
Compare the quantities of apples and strawberries given in the fruit salad recipe. Write your answer in a sentence.

art C
Compare the quantity of cherries with the total amount of fruit in the recipe. Write your answer in a sentence.

Answer 1

A

For every one part of apples, there are three parts of grapes.

B

For every one part of apples in the recipe, there are four parts of strawberries.

C

Of the eleven parts of fruit in the fruit salad, two parts are cherry.

Answer 2

The answers to each part are:

Part A.

• The quantity of apples is one-third of the quantity of grapes.

Part B.

• The quantity of apples is a quarter of the quantity of strawberries.

Part C.

• The number of cherries is two-elevenths of the total fruit.

Explanation:

To identify the answer in each case, you must remember that all the parts are equal, then:

Part A.

The parts of apples are 1 and the parts grapes are 3, so if you divide the first quantity with the second quantity you obtain:

• 1 / 3 = 1/3 (one-third)

So, the quantity of apples is one-third of the quantity of grapes or the quantity of apples is three times smaller than the quantity of grapes.

Part B.

The parts of apples are 1 and the parts of strawberries are 4, then you must divide the first quantity with the second quantity:

• 1 / 4 = 1/4 (a quarter)

In this case, the quantity of apples is a quarter of the quantity of strawberries or the quantity of apples is four times smaller than the quantity of strawberries.

Part C.

First, you must add all the part of fruit:

• 1 part apple
• 1 part orange
• 4 parts strawberry
• 2 parts cherry
• 3 parts grape

The total of fruits is 11 parts, taking into account the quantity of cherries is 2, now you can divide the number of cherries with the total parts of fruit:

• 2 / 11 = 2/11 (two-elevenths)

Now, you can see the number of cherries is two-elevenths of the total fruit.
