Find the value of $\frac{3}{5} \times\left(\frac{-5}{6}\right)-\frac{1}{8} \times \frac{4}{5}+\frac{1}{12} \times \frac{3}{5}$
Given : $\frac{3}{5}\left(\frac{-5}{6}\right)-\frac{1}{8} \times \frac{4}{5}+\frac{1}{12} \times \frac{3}{5}$
We have to simplify the fractions and add them
$=\frac{3}{5} \times \frac{-5}{6}-\frac{1}{8} \times \frac{4}{5}+\frac{1}{12} \times \frac{3}{5}$
First term: $\frac{3}{5} \times \frac{-5}{6}=-\frac{1}{2}$
$=-\frac{1}{2}-\frac{1}{8} \times \frac{4}{5}+\frac{3}{5} \times \frac{1}{12}$
Second term:$\frac{1}{8} \times \frac{4}{5}=\frac{1}{10}$
Third Term:$\frac{1}{12} \times \frac{3}{5}=\frac{1}{20}$
$=-\frac{1}{2}-\frac{1}{10}+\frac{1}{20}$
Least Common Multiple of $2,10,20: \quad 20$
Adjust Fractions based on the LCM
$=-\frac{10}{20}-\frac{2}{20}+\frac{1}{20}$
since the denominators are equal, combine the fractions:
$=\frac{-10-2+1}{20}$
$=\frac{-11}{20}$
$=-\frac{11}{20}$
