Question

Three apples plus twice as many pears add up to one-half the number of grapes in a fruit basket. How many grapes are in the basket?

Answer 1

So first of all, you would take the number of apples given (three) and multiply it by two because the question says that there are twice as many pears as there are apples. The number that we now have would be six, for 3 x 2 = 6. Now, we would take the numbers 3 and 6 and add them together (which makes nine) because they "add up to one half..." Then we would multiply the number 9 by 2 because the number nine is one half the number of grapes.

As an equation, it would be:

2(x+2x)=C

Let C be the number of grapes and x=3, so

2(3+2(3))=18
