Question

((2/5+1/10):(3/4-1/8))*3/4

Answer 1

.
$[( \frac{2}{5} + \frac{1}{10} )\div( \frac{3}{4} - \frac{1}{8} )].\frac{3}{4}= \\ \\ ( \frac{4+1}{10} )\div( \frac{6-1}{8} )]. \frac{3}{4} = \\ \\ ( \frac{5}{10} )\div( \frac{5}{8} )]. \frac{3}{4} = \\ \\ \frac{\not5}{\not10_5} . \frac{\not8^4}{\not5} ). \frac{3}{4} = \\ \\ \frac{\not4}{5} . \frac{3}{\not4} = \frac{3}{5}$
