Cross MultiplicationGiven an equation between two fractions or rational expressions, one can cross-multiply to simplify the equation or determine the value of a variable.

Cross ProductsCross-products can be used for three purposes: to compare fractions, to determine whether a proportion is true, and to solve a proportion. You can use cross-products as a shortcut method to find whether two fractions are equivalent. If the cross-products are equal, then the fractions are equivalent; if the cross-products are not equal, then the fractions are not equivalent.
