A box contains apples and oranges. The ratio of apples to oranges is 53. If there are 15 apples in the box how many oranges are in the box?

If the ratio of Apples to Oranges is 5:3, this means for every 5 Apples, there are 3 oranges. With 15 Apples in the box, we can set up a proportion: ( \frac{15 \text{ Apples}}{x \text{ oranges}} = \frac{5}{3} ). Cross-multiplying gives ( 5x = 45 ), so ( x = 9 ). Therefore, there are 9 oranges in the box.
