Problem Statement

Let a,b,c,d,e,f,g,h,ia, b, c, d, e, f, g, h, i be distinct integers from 11 to 99. The minimum possible positive value of abcdefghi\frac{a \cdot b \cdot c - d \cdot e \cdot f}{g \cdot h \cdot i} can be written as mn,\frac{m}{n}, where mm and nn are relatively prime positive integers. Find m+n.m+n.
