Question

The product of $\frac{-7}{12},\frac{-4}{9}$ & $\frac{6}{14}$ is equal to the sum of $\frac{8}{10}$ and a number. Find the number.

Answer 1

Let the required no. be $x$

According to given condition:

$\frac{-7}{12}\times \frac{-4}{9}\times \frac{6}{14}=\frac{8}{10}+x\frac{7}{12}\times \frac{4}{9}\times \frac{6}{14}=\frac{8}{10}+x\Rightarrow \frac{1}{9}=\frac{8}{10}+x\Rightarrow x=\frac{1}{9}-\frac{8}{10}=\frac{-31}{45}$
