The answer is to use Python:

import fractions

a = [insert list, deleting last item]

b = [insert list deleting first item]

for x, y in zip(b, a): print(fractions.Fraction(x, y))

The answer is to use Python:

import fractions

a = [insert list, deleting last item]

b = [insert list deleting first item]

for x, y in zip(b, a): print(fractions.Fraction(x, y))

Note: I added this answer before I saw that FrédéricC had provided an answer using SM, Sage, which is perfect. I have not deleted my answer, since I think it might help other beginners like me understand Python in addition to SM.Sage.
