Haryana Police Constable Model Paper 6

We have $\frac{7}{12},\frac{11}{18}\mathrm{and}\frac{5}{8}$ .
Let us first make the denominators same by writing the given fractions with a common denominator.
$\mathrm{LCM}\left(12,18,8\right)=72$

$\therefore \frac{7}{12}=\frac{7\times 6}{12\times 6}=\frac{42}{72}$
$\therefore \frac{11}{18}=\frac{11\times 4}{18\times 4}=\frac{44}{72}$
$\therefore \frac{5}{8}=\frac{5\times 9}{8\times 9}=\frac{45}{72}$
Writing in the descending order, we get:
$\frac{5}{8}>\frac{11}{18}>\frac{7}{12}$
Hence, the descending order would be $\frac{5}{8},\frac{11}{18},\frac{7}{12}$
