Answer:

We need 1 cup of sugar for 2 cups of bananas

Step-by-step explanation:

We can use proportions to solve this problem.  Put bananas on the top and sugar on the bottom

3 cups              2 cups bananas

-------------- = ------------------

1 1/2 cups      x cups sugar

Using cross products

3 *x = 2 *  1 1/2

Changing to decimals

3x = 2* 1.5

3x = 3

Divide by 3

3x/3 = 3/3

x=1

Answer:

1 cup

Step-by-step explanation:

You want to first find the original rate of how many cups of sugar you would need for 1 cup of bananas.

Divide 1 1/2 or 1.5 by 3 and you'll get .5 or 1/2 which is how many cups you'll need for 1 cup of bananas.

Therefore, just add 1/2 plus 1/2 since you need the answer for if you used 2 cups of bananas and you'll get 1 cup.
