stuart made a fruit juice using oranges and grapes. sixty percent of fruits are oranges. If he used a total of 60 oranges, how many grapes should he use?
60% is made of oranges and that means the other 40% needs to be grapes, but because you got lucky with 60 oranges that means for every percent there will be a fruit, so 60% is 60 oranges and 40% is 40 grapes.
