- -dfrac-7-26- - -dfrac-16-39- -160-Here LCM of -26- and - 39- is -78-So we get-160- - -dfrac-7 -times 3-26 -times 3- - -dfrac-16 -times 2-39 -times 2- -160-By further calculation-160- - -dfrac-21 - 32-78- -160- - -dfrac-11-78- -160-

Evaluate :
$$ \dfrac{7}{-26} + \dfrac{16}{39} $$

$$ \dfrac{7}{-26} + \dfrac{16}{39} $$
Here LCM of $$26$$ and $$ 39$$ is $$78$$
So we get
$$ = \dfrac{-7 \times 3}{26 \times 3} + \dfrac{16 \times 2}{39 \times 2} $$
By further calculation
$$ = \dfrac{-21 + 32}{78} $$
$$ = \dfrac{11}{78} $$
