Question

Solve: $\frac{7}{12}-\frac{1}{8}$.

Answer 1

We have, $\frac{7}{12}-\frac{1}{8}$

To solve the above equation we need to find L.C.M of the denominator.

The L.C.M of $8$ and $12=2\times 2\times 2\times 3=24$

$\begin{array}{rcl}\frac{7\times 2}{12\times 2}-\frac{1\times 3}{8\times 3}& =& \frac{14}{24}-\frac{3}{24}\\ & =& \frac{11}{24}\end{array}$

Hence, the final answer is $\frac{11}{24}$.
