405374: GYM101917 G A+B+C

Everybody knows the typical A+B problem, this one is much harder, instead of A+B it's going to be A+B+C, but with fractions.

An integer T (1<=T<=$$$10{^3}$$$), the number of test cases T lines follow, each with 3 fraction numbers, each in the form $$$\frac{n}{d}$$$ (1<=n,d<=$$$10{^6}$$$)

One line per test case, a single simplified fraction in the format $$$\frac{num}{den}$$$
