Multiple Choice

A project manager is using the resource allocation formula 6=12v+25v34v6 = \frac{1}{2}v + \frac{2}{5}v - \frac{3}{4}v to determine the total hours (vv) needed for a task. To simplify the calculation, the manager multiplies both sides of the equation by the Least Common Denominator (20). Which mathematical property justifies the step of multiplying that 20 by every individual term on the right side of the equation?
