Question

A soda shop owner told his employee to add 2 full cups and 1/5 of a cup of syrup to each gallon of soda. If there were 4 gallons of soda, how much syrup would be needed? Show your work.

Answer 1

2 and 1/5 cups for one gallon, so for four gallons, you did four times as much. 2•4=8, and 1/5•4=4/5, so you need 8 and 4/5 cups of syrup

Answer 2

To find the amount of syrup, multiply the amount of syrup per gallon by the number of gallons of soda. In this case, this would be 2 1/5 cups and 4 gallons.

2 1/5 x 4

(Changing the mixed number 2 1/5 to an improper fraction!)

11/5 x 4/1 = 44/5

(Change back to a mixed number after multiplying!)

8 4/5 cups of syrup

Hope this helps!! :)
