Question

rearrange suitably and find sum - 3/5×1/4+3/7× -1/5+1/6× - 1/8 . give the answer correct I will mark you as brainlest​

Answer 1

$\displaystyle{\rm{\bigg(\frac{3}{5}\times\frac{1}{4}\bigg)+\bigg(\frac{3}{7}\times\frac{-1}{5} \bigg)+\bigg( \frac{1}{6}\times\frac{-1}{8}\bigg) }}$

(Applied BODMAS rule)

Calculating further :-

$\displaystyle{\rm{=\bigg(\frac{3}{20} \bigg)+\bigg( \frac{-3}{35} \bigg)+\bigg( \frac{-1}{48} \bigg) }}$

Taking LCM :-

$\displaystyle{\rm{= \frac{(84 \times 3)+(-3 \times 48)+(-1 \times 35)}{1680} }}\\\\\displaystyle{\rm{=\frac{252-144-35}{1680} }}\\\\\boxed{\color{lime}{\displaystyle{\rm{= \frac{73}{1680} }}}}$

Answer 2

$\huge\underline\mathtt\color{gold}SolutioN:$

$\displaystyle{\rm{\bigg(\frac{3}{5}\times\frac{1}{4}\bigg)+\big(\frac{3}{7}\times\frac{-1}{5} \bigg)+ \bigg( \frac{1}{6}\times\frac{-1}{8}\bigg) }}$

$\displaystyle{\rm{\bigg(\frac{3}{20}\bigg)+\bigg(\frac{-3}{35}\bigg)+\bigg(\frac{-1}{48}\bigg) }}$

By doing LCM,

${\implies{\tt{\frac{(84 × 3) + (-3 × 84) + ( -1 × 35)}{1680}}}}$

${\implies{\tt{\frac{252 - 144 - 35}{1680}}}}$

$\large\underline{\underline{\boxed{\mathtt{\color{teal}{\frac{73}{1680}}}}}}{\color{olive}{\bigstar}}$
