#### Answer

(d) LCM

#### Work Step by Step

To get rid of the fractions in an equation, the LCM (least common multiple) of the denominators must be multiplied to both sides of the equation.
Example
For the equation $\frac{1}{2}y=\frac{1}{3}x-3$, multiplying the LCM of $6$ to both sides of the equation gives:
$6(\frac{1}{3}x)=6(\frac{1}{3}x-3)
\\2x=2x-18$
