Question

Simplify (-1/3)- {1/ (2/3 *5/7)+8-[5-1/2- 1/4]} answers

Answer 1

$\big(\frac{-1}{3}\big) - \{ \frac{1}{\Big( \frac{2}{3} \times \frac{5}{7} \Big) } + 8 - [5- \frac{1}{2} - \frac{1}{4} ]\}$

$= \big(\frac{-1}{3}\big) - \{ \frac{1}{\Big( \frac{10}{21} \Big) } + 8 - [\frac{20-2-1}{8} ]\}$

$= \big(\frac{-1}{3}\big) - \{\frac{21}{10}+ 8 - \frac{17}{8} \}$

$= \big(\frac{-1}{3}\big) - \{ \frac{84+320-85}{40}\}$

$= \frac{-1}{3} - \frac{319}{40} \\= \frac{-40-957}{120} \\= \frac{-997}{120}$

Therefore.,

$\red{\big(\frac{-1}{3}\big) - \{ \frac{1}{\Big( \frac{2}{3} \times \frac{5}{7} \Big) } + 8 - [5- \frac{1}{2} - \frac{1}{4} ]\} }$

$\green {= \frac{-997}{120}}$
