Create a common denominator when adding or subtracting
...
Is this 2%2F7+%2B+3%2F5+%2B+1%2F3? or 2%2F4%2B3%2F5-1%2F3
...
Either way, use 7*5*3 = 105 as the common denominator
so,
%282%2F7%29%2815%2F15%29+%2B+%283%2F5%29%2821%2F21%29 + or - %281%2F3%29%2835%2F35%29
...
%2830%2F105%29+%2B+%2863%2F105%29 + or - %2835%2F105%29
