Which of the following fractions is the smallest?

​$$\frac{17}{21} , \frac{9}{11}, \frac{16}{19}, \frac{13}{15}$$​​

Correct option is A

Given:

​$$\frac{17}{21} , \frac{9}{11}, \frac{16}{19}, \frac{13}{15}$$​​

Solution:

Here the fractions are $$\frac{17}{21} , \frac{9}{11}, \frac{16}{19}, \frac{13}{15}$$ in decimal forms​

​$$\frac{17}{21} =0.8095$$​​

​$$\frac{9}{11} =0.8181$$​​

​$$\frac{16}{19} =0.8421$$​ 

​$$\frac{13}{15}=0.8666$$​​

The smallest decimal is 0.8095 hence $$\frac{17}{21}$$​ is smallest
