Frances uses 2/3 cup of pineapple juice for every 1/3 cup of orange juice to make a smoothie. enter the number of cups of pinapple juice frances uses for 1 cup of orange juice

Write and solve an equation of ratios to answer this question:

Pineapple   Orange

Juice            Juice

   x                1 cup

   =    

 2/3 c              1/3 c

Then (1/3 c)x = (2/3) c^2.

Multiplying both sides by (3/1) will clear the fractions:

x = (3/1)(2/3) c = 2 cups (answer)
