Question

Hi all...Please help me and give correct answer... and do not write like sorry or I don't know....if you don't know please don't give answers 3/4-[1/2 of 4-(2/5+1/5)×9/7

Answer 1

$\frac{3}{4} - [ \frac{1}{2} \:of \: 4 - \Big(\frac{2}{5} + \frac{1}{5}\Big)] \times \frac{9}{7}$

$= \frac{3}{4} - [ \frac{1}{2} \times 4 - \Big(\frac{2+1}{5} \Big)] \times \frac{9}{7}$

$= \frac{3}{4} - [ 2 - \frac{3}{5}] \times \frac{9}{7}$

$= \frac{3}{4} - [ \frac{10-3}{5}] \times \frac{9}{7}$

$= \frac{3}{4} - \frac{7}{5} \times \frac{9}{7}$

$= \frac{3}{4} - \frac{9}{5}$

$= \frac{15-36}{20}$

$= \frac{-21}{20}$

Therefore.,

$\red{\frac{3}{4} - [ \frac{1}{2} \:of \: 4 - \Big(\frac{2}{5} + \frac{1}{5}\Big)] \times \frac{9}{7}}$

$\green { = \frac{-21}{20} }$
