First convert fractions to improper fractions:
%283%2A8%2B1%29%2F8-%282%2A20%2B3%29%2F20
25%2F8-43%2F20 Now we need to get the common denominator (which is 40)
%285%2F5%29%2825%2F8%29-%282%2F2%29%2843%2F20%29
125%2F40-86%2F40
%28125-86%29%2F40
39%2F40
So in other words 3 and 1/8 minus 2 and 3/20 reduces to 39%2F40
