If the ratio of apples to oranges is 3:4 and you have 21 apples, how many oranges?

Ratios show how two quantities relate and how to scale them together. If apples to oranges is 3 to 4, then for every 3 apples there are 4 oranges. You have 21 apples, which is 7 groups of 3 (21 ÷ 3 = 7). For each group, there are 4 oranges, so total oranges = 7 × 4 = 28. Another way to see it is to scale by the factor 4/3: 21 × (4/3) = 28. So there are 28 oranges.
