Answer 2

Answer: The simplified value is -371/60

Step-by-step explanation:

(-1/3)-{1÷(2/3×5/7)+8-[5-1/2-1/4]}​

⇒  ($\frac{-1}{3}$) - { 1 ÷ $(\frac{2}{3}$ × $\frac{5}{7})$ $+8-[5-\frac{1}{2}-\frac{1}{4} ]$ }

Start with solving inner most brackets.

Solving () bracket inside the { } bracket

⇒  ($\frac{-1}{3}$) - { 1 ÷ $(\frac{10}{21} )$ $+8-[5-\frac{1}{2}-\frac{1}{4} ]$ }

⇒  ($\frac{-1}{3}$) - { 1 ÷ $\frac{10}{21}$ $+8-[5-\frac{1}{2}-\frac{1}{4} ]$ }

Solving [ ] bracket inside the { } bracket.

⇒  ($\frac{-1}{3}$) - { 1 ÷ $\frac{10}{21}$ $+8-[\frac{20 - 2 -1}{4} ]$ }

⇒  ($\frac{-1}{3}$) - { 1 ÷ $\frac{10}{21}+8 - [\frac{17}{4} ]$ }

⇒  ($\frac{-1}{3}$) - { 1 ÷ $\frac{10}{21}+8 - \frac{17}{4}$ }

Simplifying { } bracket using DMAS rule, i.e., first solving division, then multiplication, then addition and finally subtraction.

⇒  ($\frac{-1}{3}$) - { 1 ×  $\frac{21}{10}+8 - \frac{17}{4}$ }

⇒  ($\frac{-1}{3}$) -  { $\frac{21}{10}+8 - \frac{17}{4}$ }

⇒  ($\frac{-1}{3}$) -  { $\frac{117}{20}$ }

⇒  $\frac{-1}{3}-\frac{117}{20}$

⇒  $\frac{-20}{60}-\frac{351}{60}$

⇒  $-\frac{371}{60}$
