- -dfrac-7-27- - -dfrac-11-18- -Here LCM of -27- and - 18 - is - 54 -160-So we get-160- - -dfrac-7 -times 2-27 -times 2- - -dfrac-11 -times 3-18 -times 3- -By further calculation-160- - -dfrac-14 - 33-54- -160- - -dfrac-19-54- -160-

Evaluate :
$$ \dfrac{7}{-27} + \dfrac{11}{18} $$

$$ \dfrac{7}{-27} + \dfrac{11}{18} $$
Here LCM of $$27$$ and $$ 18 $$ is $$ 54 $$
So we get
$$ = \dfrac{7 \times 2}{-27 \times 2} + \dfrac{11 \times 3}{18 \times 3} $$
By further calculation
$$ = \dfrac{-14 + 33}{54} $$
$$ = \dfrac{19}{54} $$
