Question

Simplify : $18\frac{9}{14}-7\frac{6}{7}$

Answer 1

Converting the mixed fraction into improper fraction :

$18\frac{9}{14}=\frac{261}{14}$

and $7\frac{6}{7}=\frac{55}{7}$

Now, taking LCM of $(7,14)=14$

therefore on simplifying and putting the respective values ,we get :

$=18\frac{9}{14}-7\frac{6}{7}$

$=\frac{261}{14}-\frac{55}{7}$

$=\frac{261-110}{14}=\frac{151}{14}$

$=\frac{151}{14}=10\frac{11}{14}$

Hence, the required answer on simplifying $18\frac{9}{14}-7\frac{6}{7}$ is $10\frac{11}{14}$.
