| Question | Answer |
| \(\frac {2}{3}\) + \(\frac {3}{4}\) = | = \(\frac {8+9}{3·4}\)=\(\frac {17}{12}\)=\(1\frac {5}{12}\) |
| \(\frac {1}{4}\) + \(\frac {2}{3}\) = | = \(\frac {3+8}{4·3}\)=\(\frac {11}{12}\) |
| \(\frac {1}{2}\) + \(\frac {3}{4}\) = | = \(\frac {4+6}{2·4}\)=\(\frac {5}{4}\)=\(1\frac {1}{4}\) |
| \(\frac {1}{2}\) + \(\frac {1}{3}\) = | = \(\frac {3+2}{2·3}\)=\(\frac {5}{6}\) |
| \(\frac {2}{3}\) + \(\frac {1}{2}\) = | = \(\frac {4+3}{3·2}\)=\(\frac {7}{6}\)=\(1\frac {1}{6}\) |
| \(\frac {1}{3}\) + \(\frac {3}{4}\) = | = \(\frac {4+9}{3·4}\)=\(\frac {13}{12}\)=\(1\frac {1}{12}\) |
| \(\frac {3}{4}\) + \(\frac {1}{5}\) = | = \(\frac {15+4}{4·5}\)=\(\frac {19}{20}\) |
| \(\frac {2}{5}\) + \(\frac {1}{3}\) = | = \(\frac {6+5}{5·3}\)=\(\frac {11}{15}\) |

| \(\frac {2}{3}\) + \(\frac {3}{5}\) = | = \(\frac {10+9}{3·5}\)=\(\frac {19}{15}\)=\(1\frac {4}{15}\) |
| \(\frac {3}{5}\) + \(\frac {1}{3}\) = | = \(\frac {9+5}{5·3}\)=\(\frac {14}{15}\) |
| \(\frac {3}{5}\) – \(\frac {1}{3}\) = | = \(\frac {9–5}{5·3}\)=\(\frac {4}{15}\) |
| \(\frac {2}{3}\) – \(\frac {1}{4}\) = | = \(\frac {8–3}{3·4}\)=\(\frac {5}{12}\) |
