Answer
Given $\frac{2}{3}-\frac{1}{2}$ Here LCM of 3 and 2 is 6. Fractional unit for both fractions should be $\frac{1}{6}$ $\begin{aligned} \therefore \quad & \frac{2 \times 2}{3 \times 2}-\frac{1 \times 3}{2 \times 3} \\ & =\frac{4}{6}-\frac{3}{6} \\ & =\frac{4-3}{6} \\ & =\frac{1}{6}\end{aligned}$
