Numbers \([ - \frac{{11}}{{20}},\;\frac{7}{{ - 15}},\;\frac{{17}}{{ - 30}}\;and - \frac{3}{{10}}]\) are written in descending order as
1
\(\frac{{17}}{{ - 30}}\; > \; - \frac{{11}}{{20}}\; > \; - \frac{3}{{10}}\; > \;\frac{7}{{ - 15}}\)
2
\( - \frac{3}{{10}}\; > \;\frac{7}{{ - 15}}\; > \; - \frac{{11}}{{20}}\; > \;\frac{{17}}{{ - 30}}\)
3
\( - \frac{3}{{10}}\; > \; - \frac{{11}}{{20}}\; > \;\frac{7}{{ - 15}}\; > \;\frac{{17}}{{ - 30}}\)
4
\( - \frac{{11}}{{20}}\; > \;\frac{{17}}{{ - 30}}\; > \; - \frac{3}{{10}}\; > \;\frac{7}{{ - 15}}\)
