A proportion is a statement that two ratios or rates are equal.
Rates are ratios ... Speed is a rate of distance per unit of time... ratio of distance to time. Proportions are two equal ratios, whether they are rates or not.
An equation that sets two fractions equal to each other is called a proportion. In a proportion, the cross products of the fractions are equal. For example, if you have the proportion ( \frac{a}{b} = \frac{c}{d} ), then ( ad = bc ). Proportions are commonly used in solving problems involving ratios and rates.
Rate1 = Rate2, I suppose.
Rates are ratios that are renamed so that one of the numbers is 1. It is usually the denominator of the original ratio.
