1320
this is how you do it: 1 3/5 = 8/5 2/3 = 2/3 so then you find a lowest common denominator (LCD) which in this case is 15 and you put each fraction with the denominator as 15 and multiply the numerator by the same thing you multiplyed the denominator by so 8/5 = 24/15 2/3 = 10/15 then you subtract 24/15-10/15 = 14/15 which is your answer!!!
