Option 2 : 11/20

**Calculation:**

Converting all the fraction to the decimal form,

5/8 = 0.625

9/10 = 0.9

Checking the option which is not in this range

7/9 = 0.78

11/20 = 0.55

16/21 = 0.76

9/11 = 0.81

From the options 0.55 is not in the range of 0.625 and 0.9

**∴ 11/20 does not lie between 5/8 and 9/11**
