Two equal ratios joined by an equal sign are called a proportion. For example, if you have the ratios ( \frac{a}{b} ) and ( \frac{c}{d} ), they form a proportion when written as ( \frac{a}{b} = \frac{c}{d} ). This indicates that the two ratios are equivalent, meaning that the cross products ( a \cdot d ) and ( b \cdot c ) are equal. Proportions are often used to solve problems involving similar figures or scaling.
