  STEP 1: For adding the fractions with different denominators.

  ---

  
  

  Both fractions have different denominators and thus are unable to be easily added together. Find the least common multiple (LCM) of the denominators.

  STEP 2: Change the unlike denominators to like denominators.

  The LCM is the same as the LCD (Least Common Denominator). Multiply the numerator and the denominator of each fraction by the LCD so that the fractions will have like denominators. Then add the fractions.
