    well subtracting a negative is same as adding, 2 neg make a pos find LCM of 35 and 40 35 = 7*5 40=8*5 LCm = 5*8*7 = 280 35*8 = 280 40*7 = 280 -8/280 + 63/280 =55/280 =11/56

    ok, so the only way you will have to form the same LCD is by mult. (8/8), its just one, but it allows you to share a common denominator so that you can add/subtract the two fractions.
