Answer:


(10)/(43)

Explanation:

sop : jr = 2 : 3

jr : sen = 5 : 6

find the LCF of jr → LCF of 3 & 5 → which is equals to 15

sop : jr = 2 : 3 = 10 : 15

jr : sen = 5 : 6 = 15 : 18

-----------------------------------

sop : jr : sen = 10 : 15 : 18 → the whole team = 10 + 15 + 18 = 43

fraction sop to the whole team =
(10)/(43)
