Simplify the following.
$\frac{-7}{ 7} + \frac{3}{ 9} + \frac{1}{ 6}$

Given:

$\frac{-7}{ 7}  + \frac{3}{ 9}  +  \frac{1}{ 6}$

To do: Simplify the given equation.

Solution:

 $\frac{-7}{ 7}  + \frac{3}{ 9}  +  \frac{1}{ 6}$

$-1+\frac{1}{3}+\frac{1}{6}$

LCM of 6 and 3 is 6

$\frac{-6+2+1}{6}$

$\frac{-3}{6}$

$\frac{-1}{2}$

Therefore , the value of the equation is $\frac{-1}{2}$
