An equation stating that two ratios are equal is called a proportion. It is typically written in the form ( \frac{a}{b} = \frac{c}{d} ), where ( a ), ( b ), ( c ), and ( d ) are numbers, and ( b ) and ( d ) are not zero. Proportions can be used to solve for unknown values and are based on the concept that the cross-products are equal, meaning ( a \cdot d = b \cdot c ).
