Addition of Fractions

Examples: 1. Add the fractions \(\frac{2}{3}\) and \(\frac{4}{5}\). Solution: \(\frac{2}{3} + \frac{4}{5} = \frac{5 × 2 + 3 × 4}{15} \\ = \frac{10 + 12}{15} = \frac{22}{15} = 1\frac{7}{15}\). 2. Add the fractions \(4\frac{3}{11}\), \(7\frac{1}{3}\). Solution: \(4\frac{3}{11} + 7\frac{1}{3} = \frac{47}{11} + \frac{22}{3} \\ = \frac{47(3) + 11(22)}{33} \\ = \frac{141 + 242}{33} = \frac{383}{33}\) = \(11\frac{20}{33}\) (in mixed fraction). (Note: In this method, we first change the mixed fractions to Improper fractions before adding).
