Mary is making a gallon of iced which requires 5 cups of iced tea mix. She only has a 1/4 cup sized measuring cup. How many scoops will she have to get the correct amount of mix?

Divide 1/4 into 5. You can obtain the same answer by multiplying 5 by 4/1, and that answer is 20.

20 scoops, answer.

1/4 cup 4 times makes 1 cup.

1/4 cup 8 times makes 2 cups.

1/4 cup 12 times makes 3 cups

1/4 cup 4•4=16 times makes 4 cups so

1/4 cup 4•5=20 times makes 5 cups.

She will need to scoop 20 times
