Answers
Given : Tara answered 5/7 of the problems correctly and Julia answered 7/10 of them correctly.
To Find : who got the higher grade and by how much
Solution:
Let say Problems = 70N
Tara answered 5/7 correctly = (5/7)70N = 50N
Julia answered 7/10 correctly = (7/10)70N = 49N
50 > 49
Hence Tara gets higher grade
50N - 49N = N
Tara gets higher grade by N/70N = 1/70
Tara gets 1/70 higher grade
