Answer:

5/11.

Step-by-step explanation:

S = 1/1.3 + 1/3.5 + 1/5.7 + 1/7.9 + 1/9.11

S = 1/2 [ (1-1/3)+(1/3-1/5)+(1/5-1/7)+(1/7-1/9)+(1/9-1/11)]

All the terms excluding 1 and -1/11 will be cancelled.

S = 1/2[1-(1/11)]

S = 1/2 * 10/11 = 5/11...

Its Sum Formula Is (Sₙ = n/2n+1).

For n=5 .  S₅ = 5 / 11.
