A bowl contains many kinds of fruit. In the bowl there are twice as many pears then there are oranges, and twice times as many plums as oranges. If the total number of pieces of fruit is X, then how many oranges are in the bowl as a fraction of X
Pick one.
A) X/2  B) X/3  C) X/4  D) X/5  E) X/6
Since X equals the number of fruit, X = pears + oranges + plums.   Since there are twice as many pears as oranges, then pears = 2*oranges.   Since there are twice as many plums as oranges, then plums = 2*oranges   Hence X = 2*oranges + oranges + 2*oranges, which simplifies to X = 5*oranges   Thus Oranges = X/5   Answer: X/5
