What is the correct descending order of the following ratios?

​$$\frac{17}{30}, \ \frac{7}{15}, \ \frac{27}{50}, \ \frac{11}{20}$$​​

Correct option is B

​$$\textbf{Solution:} \\ \frac{17}{30} = 0.5666 \\\ \\\frac{7}{15} = 0.4666 \\\ \\\frac{27}{50} = 0.54 \\\ \\\frac{11}{20} = 0.55 \\\ \\$$​​

So, the correct answer is $$\frac{17}{30} > \frac{11}{20} > \frac{27}{50} > \frac{7}{15}$$​​
