The number of cups of fruit salad that will be in each container is; 3³/₄ cups of fruit salad
<h3>How to divide fractions?</h3>We are given the table showing the amount of cups of each ingredient as attached.
From the table we see that;
Amount of cups of Pineapple = 2³/₄
Amount of cups of Strawberries = 2¹/₂
Amount of cups of Bananas = 1¹/₂
Amount of cups of Blueberries = 2¹/₄
Now, converting each of the given fractions to improper fractions gives;
11/4, 5/2, 3/2, 9/2
Summing up all the fractions will give us;
11/4 + 5/2 + 3/2 + 9/2
(1/4)(11 + 10 + 6 + 18) = 45/4
Now, since this total amount will be divided by 3, we will have;
45/4 ÷ 3
= 45/4 * 1/3
= 15/4 = 3³/₄ cups of fruit salad
