Find the value: $(\frac{3}{7}) + (\frac{- 6}{11}) + (\frac{- 8}{21}) + (\frac{5}{22})$

Open in App

Solution

Compute the given expression
Given, $(\frac{3}{7}) + (\frac{- 6}{11}) + (\frac{- 8}{21}) + (\frac{5}{22})$
L.C.M. of $(7, 11, 21, 22) = 462$
$∴ (\frac{3}{7}) + (\frac{- 6}{11}) + (\frac{- 8}{21}) + (\frac{5}{22}) = \frac{(66 \times 3) - (42 \times 6) - (22 \times 8) + (21 \times 5)}{462} = \frac{198 - 252 - 176 + 105}{462} = \frac{- 125}{462}$
Hence, the value of $(\frac{3}{7}) + (\frac{- 6}{11}) + (\frac{- 8}{21}) + (\frac{5}{22})$ is $\frac{- 125}{462}$
