Monica and Veronica are making strawberry pineapple smoothies. For every 1 cups of strawberries, they use

pineapple. Monica and Veronica have already put 1 cup of pineapple into the blender. The girls cannot agree how many

cups of strawberries to add to the blender to keep the same ratio, so they each did some work to determine the number

of cups of strawberries necessary for the smoothie.

Answer 1

For 1 cup of pineapple 1 .5 cups of strawberries are used.

Explanation:

This question can be solved by using ratios

Strawberry : Pineapple

1 cup : 2/3 cup

x cup ; 1 cup

Using the cross product rule

2/3 * x= 1*1

x= 1*1 ÷ 2/3

x= 1*3/2= 1 1/2= 1.5

For 2 cups of pineapple 3 cups of strawberries are used.

For 1 cup of pineapple 1 .5 cups of strawberries are used.

For 3 cups of pineapple 4.5 cups of strawberries are used.
