Ben has some apples, pears and oranges. 2/5 of the fruits are apples and the ratio of the number of pears to the number of oranges is 2:7. What is the number of apples to the number of pears to the number of oranges?

Let the number of fruits be x,

the number of pears be y the number of oranges be z.

y:z = 2:7

                           => y = 2/9 (3/5x)
y + z = x (1 - 2/5)     z = 7/9 (3/5x)

Apples : 2/5x

Pears: 2/15x

Oranges: 7/15x

2/5x: 2/15x: 7/15x = 6:2:7
