Solving Fraction Equations with Multiplication and Division Example 1: Solve Divide both sides by 2/3 to isolate the variable. Original equation Solution Remember: * The goal when solving equations is to isolate the variable. * We isolate the variable by completing inverse operation(s). * What you do to one side of the equation, you MUST do to the other! Rewrite as multiplication using the reciprocal of the divisor on both sides. Then, multiply. Cancel out the 6s and reduce 42/2.

Solving Fraction Equations with Multiplication and Division Example 2: Solve Divide both sides by 2 to isolate the variable. Original equation Solution Rewrite as multiplication using the reciprocal of the divisor on both sides. Then, multiply. Cancel out the 2s. Remember: * The goal when solving equations is to isolate the variable. * We isolate the variable by completing inverse operation(s). * What you do to one side of the equation, you MUST do to the other!

Solving Fraction Equations with Multiplication and Division Example 3: Solve Divide both sides by 5/6 to isolate the variable. Original equation Solution Rewrite as multiplication using the reciprocal of the divisor on both sides. Then, multiply. Cancel out the 30s. And write 24/5 as a mixed number. Remember: * The goal when solving equations is to isolate the variable. * We isolate the variable by completing inverse operation(s). * What you do to one side of the equation, you MUST do to the other!
