Combining using the least common denominator

WebWell, the problem you gave have the same concept the video above described. We need to have a common denominators first in order to add the two fractions. Since x is anything, the only multiple of (x+2) and (x+1) is (x+1) (x+2). You multiply the first fraction by (x+1) and will get (x+1)/ (x+2) (x+1). The second fraction can be multiplied by x+2. WebHere are the steps to follow: Find the Least Common Multiple of the denominators (which is called the Least Common Denominator ).
