Explanation / Answer

Say for example you have: 1/2 +1/3    -the first thing you would do is make ithave a common denominator (bottom number)       - The LCM (least commonmultiple) of 2 and 3 is 6 so you want to multiply the top andbottom by whatever number gives you a 6 in the denominator          - 1/2(3/3) + 1/3 (2/2)          - thenyou have:             -3/6 + 2/6 and then you can multiply across the numerator                -3/6 +2/6 = (3+2)/6 = 5/6 answer is 5/6 I hope i was helpful.
