Adding and subtracting fractions with different denominators :D

Answer:
find the LCM of denominators and multiply the last answers of LCM for example take 1/3 and 1/2 it's LCM is 6
1/3 = 1×2/3×2 = 2/6
1/2 = 1×3/2×3 = 3/6
then subtract 3-2/6 = 1/6 this is subtraction
instead of subtracting just add it
