Question

8 of the students went to see live animals what fraction part of the group is that

Answer 1

To answer the question you need to know how many students n all are in the group then 8 would be the numerator and the number of all the students in the group would be the denominator

Answer 2

In order to answer that question we would have to know how many people are in the group
For example: if there are ten people in the group then the fraction would be 8/10
If there are 20 people in the group then the fraction would be 8/20
I hope this helped
