Alexis is making a cake and needs 4/5 cups of brown sugar for every 3/4 pounds of flour. How much brown sugar will be needed for 1 pound of flour?
SHOW YOUR WORK

Answers

Answer:

16/15

Step-by-step explanation:

Ratio: 3/4 : 4/5

Whole number ratio: 15 : 16

You need to divide both sides by 15 so you can turn 15 to 1

Divide both sides of the ratio by 15: 1 : 16/15

So, for 1 pound of flour, you need 16/15 pounds of brown sugar for a cake.
