Steps to Solving Rational Equations Using Cross Multiplication

• Simplify the equation to get it in the form a/b = c/d, where a, b, c, and d are numbers, variables, or algebraic expressions.

• Use cross multiplication to rewrite the equation as ad = bc.

• Solve the resulting equation.

Answer 2

Answer:

Step-by-step explanation:

Given an equation like:

{\displaystyle {\frac {a}{b}}={\frac {c}{d}}}\frac a b = \frac c d

(where b and d are not zero), one can cross-multiply to get:

{\displaystyle ad=bc\qquad \mathrm {or} \qquad a={\frac {bc}{d}}.}ad = bc \qquad \mathrm{or} \qquad a = \frac {bc} d.

In Euclidean geometry the same calculation can be achieved by considering the ratios as those of similar triangles.
