Evaluate: $-1+\frac{2}{-3}+\frac{5}{6}$
✓
Answer
$-1+\frac{2}{-3}+\frac{5}{6}$
| 2 | 3,6 |
| 3 | 3,3 |
| 1,1 |
L.C.M. of 3 and $6=2 \times 3=6$
$ \begin{aligned} & \Rightarrow \frac{-1 \times 6}{1 \times 6}-\frac{2 \times 2}{3 \times 2}+\frac{5 \times 1}{6 \times 1} \\ & (\because \text { L.C.M. of } 3 \text { and } 6=6) \end{aligned} $
$ \Rightarrow \frac{-6-4+5}{6} $
$ =\frac{-10+5}{6}=-\frac{5}{6} $
