Fractions $\frac{3}{4}, \frac{2}{3}, \frac{5}{6}, \frac{11}{18}$ when written in descending order are:

$\frac{5}{6}, \frac{3}{4}, \frac{2}{3}, \frac{11}{18}$

We have,

$\frac{3}{4}, \frac{2}{3}, \frac{5}{6}, \frac{11}{18}$ 

Take the  LCM of denominators of all the fractions and solve,

LCM = 36

$\frac{3}{4}$ × 36 = 27

$\frac{2}{3}$ × 36 = 24

$\frac{5}{6}$ × 36 = 30

$\frac{11}{18}$ × 36 = 22

We can arrange them according to the result obtained,

The correct answer is Option (4) → $\frac{5}{6}, \frac{3}{4}, \frac{2}{3}, \frac{11}{18}$
