Answer:
14 1/2
Step-by-step explanation:
To find out how many cups of punch Helen made, you simply add together the amounts of grapefruit juice and lemon-lime soda.
10 cups of grapefruit juice + 4 1/2 cups of lemon-lime soda
To add these together, you might want to convert the mixed fraction (4 1/2) into a regular fraction:
4 1/2 = 4 + 1/2 = 9/2
So, the sum becomes:
10 cups + 9/2 cups
To add these, you need a common denominator. Multiplying 10 by 2/2, you get:
20/2 cups + 9/2 cups = 29/2 cups
Since 29/2 is an improper fraction, you could also express it as a mixed number:
29 ÷ 2 = 14 remainder 1
So, 29/2 is equal to 14 1/2.
Therefore, Helen made 14 1/2 cups of punch.
