Answer:  Fraction of twins =  Fractions of triplets =
 Fractions of triplets =  Fractions of quadruplets =
 Fractions of quadruplets = 
Step-by-step explanation:
Since we have given that 
Number of set of twins = 5
Number of sets of triplets = 2
Number of sets of quadruplets = 1
Total number of sets is given by

Now, we need to find the fraction of those students.
So, Fraction of twins is given by

Fractions of triplets is given by

Fractions of quadruplets is given by
