Consider the mixed fraction like 4 5/3 and 6 4/3 first convert the mixed fractions into improper fractions. so it is (4*3+5)/3 and (6*3+4)/3 = 17/3 - 22/3 so the result after subtracting the numerators the result is -5/3.If the denominators are different then try to make it equal by taking L.C.M then subtract.
