Solution

Verified by Toppr

Rational numbers can be arranged in descending
all ascending order by making their denominates equal.
Therefore, LCM of 30, 15, 10 and 5 is 30.
So, $\frac{- 17}{30} = \frac{- 17}{30}; \frac{- 7}{10} = \frac{21}{30}$
$\frac{- 11}{15} = \frac{- 22}{30}; \frac{3}{5} = \frac{18}{30}$
so, in descending order $\to$
$\frac{18}{30} > \frac{- 17}{30} > \frac{- 21}{30} > \frac{- 22}{30}$
$= \frac{3}{5} > \frac{- 17}{30} > \frac{- 7}{10} > \frac{- 11}{15}$
