If the fraction 8/6, 7/5, 18/13, 9/5 and 7/11 are arranged in descending order of their values, which one will be the second ?
A). 1/9
B). 2/7
C). 3/4
D). 7/5
7/5
8/6 = 1. 333, 7/5 = 1.4, 18/13 = 1.384
9/5 = 1.8 and 7/11 = 0.636
Therefore, Descending order is 9/5 > 7/5 > 18/13 > 8/6 > 7/11
Therefore Second fraction is 7/5
