Solving One-Step Multiplication Equations with Fractions

The video tutorial explains how to solve equations with fractional coefficients by using reciprocals. It demonstrates three examples: solving two-fifths x = 10, 14 = seven-thirds b, and one-sixth a = two-thirds. The key technique involves multiplying both sides of the equation by the reciprocal of the fraction to isolate the variable, simplifying the equation to find the solution.

What is the first step to solve the equation 2/5x = 10?
