here is the original problem
%28%281_and_%281%2F2%29+%2B+3%2F4%29%29+%2F+%28%283_and_%281%2F4%29+-+1%29%29+
step 1 - turn all into mixed to get
%28%283%2F2%29+%2B+%283%2F4%29%29%2F+%28%2813%2F4%29+-+1%29%29
step 2 - add numerator and denominator fractions to get
%289%2F4%29+%2F+%289%2F4%29
this is just 1.
