Question

Solve : $\frac{\frac{1}{4}+\frac{2}{4}}{1-\frac{1}{4}\times \frac{2}{4}}$

Answer 1

$\frac{\frac{1}{4}+\frac{2}{4}}{1-\frac{1}{4}\times \frac{2}{4}}$

$=\frac{\frac{1}{4}+\frac{1}{2}}{1-\frac{1}{4}\times \frac{1}{2}}$

$=\frac{\frac{1+2}{4}}{1-\frac{1}{8}}$

$=\frac{\frac{3}{4}}{\frac{8-1}{8}}$

$=\frac{\frac{3}{4}}{\frac{7}{8}}$

$=\frac{3}{4}\times \frac{8}{7}$

$=\frac{3}{4}\times \frac{8}{7}$

$=\frac{3}{1}\times \frac{2}{7}$

$=\frac{6}{7}$
