Adding fractions with unlike denominators - free online math help

Learn how to add and subtract fractions whose denominators are not the same. Recall that when we want to add or subtract fractions having the same denominator, we add the numerators and retain the (common) denominator. This is different when the fractions have different denominators. When adding fractions with different denominators, we convert the fractions to equivalent fractions having the same denominator. This is achieved by finding the LCM of the different denominators (the least number that the denominators can divide without remainder). We then multiply the denominators by a number which will yield the LCM. You will also multiply the numerator by the same number with which you multiplied the denominator. Notice now that the fractions have the same denominator. We can now add or subtract the numerators retaining the common denominator.
