STEP 1: Subtract the fractions.
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 both the numerator and the denominator by the LCD so that the fractions will have like denominators. If a fraction's denominator is already the LCD, then it does not need to be converted.
-
STEP 3: Simplify and subtract.
Convert the fraction to have like denominators. Then subtract.
-
STEP 4: Find the solution.
Both fractions now have like denominators so they can be subtracted.
