Explanation:
what is the real problem definition ?
is there now an absolute value around the top "-2", or not ?
in any case, remember, when we divide 2 rational numbers like this :
a/b / c/d
the result is
"outer multiplication" over "inner multiplication" :
a×d / b×c
as alternative you can always also say
a/b / c/d = a/b × d/c = a×d / b×c
so,
if the problem is
3/-2 / |-4/-2|
the result is
3×2 / 4×-2 = 6/-8 = - 3/4
if the problem is
3/|-2| / |-4/-2|
the result is
3×2 / 4×2 = 6/8 = 3/4
please pick the solution based on the actual problem.
