Helen mixed together 10 cups of grapefruit juice and 4 1/2 cups of lemon-lime soda to make punch. How many cups of punch did Helen make?

Sagot :

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.
