Proportion
A proportion says two ratios are equal, like 2/3 = 4/6. Solving a proportion with a missing number, like 2/3 = ?/9, means finding what the ratio was scaled by: since 3 scales up to 9 by multiplying by 3, the missing number must be 2 x 3 = 6, a strategy also used to convert between measurement units.
