Solve a One Step Equation by Multiplying by Reciprocal (a/b)x=c/d (Example)

Curated and Reviewed by Lesson Planet

Flip the switch to learn about flipping coefficients when solving equations. Pupils review how to solve equations of the form (a/b)x = c/d by watching a video. They see two different ways to achieve this goal: by multiplying by the reciprocal and by multiplying through by the least common denominator to clear the fractions.
