Заполним таблицу:
| a | b | a + b | a - b |
|---|---|---|---|
| $$\frac{13}{32}$$ | $$\frac{9}{32}$$ | $$\frac{13}{32} + \frac{9}{32} = \frac{13+9}{32} = \frac{22}{32} = \frac{11}{16}$$ | $$\frac{13}{32} - \frac{9}{32} = \frac{13-9}{32} = \frac{4}{32} = \frac{1}{8}$$ |
| $$\frac{82}{125}$$ | $$\frac{3}{47}$$ | $$\frac{82}{125} + \frac{3}{47} = \frac{82 \cdot 47 + 3 \cdot 125}{125 \cdot 47} = \frac{3854 + 375}{5875} = \frac{4229}{5875}$$ | $$\frac{82}{125} - \frac{3}{47} = \frac{82 \cdot 47 - 3 \cdot 125}{125 \cdot 47} = \frac{3854 - 375}{5875} = \frac{3479}{5875}$$ |
| $$\frac{27}{44}$$ | $$\frac{27}{44}$$ | $$\frac{27}{44} + \frac{27}{44} = \frac{27+27}{44} = \frac{54}{44} = \frac{27}{22}$$ | $$\frac{27}{44} - \frac{27}{44} = \frac{27-27}{44} = \frac{0}{44} = 0$$ |
| $$\frac{14}{17}$$ | $$\frac{28}{123}$$ | $$\frac{14}{17} + \frac{28}{123} = \frac{14 \cdot 123 + 28 \cdot 17}{17 \cdot 123} = \frac{1722 + 476}{2091} = \frac{2198}{2091}$$ | $$\frac{14}{17} - \frac{28}{123} = \frac{14 \cdot 123 - 28 \cdot 17}{17 \cdot 123} = \frac{1722 - 476}{2091} = \frac{1246}{2091}$$ |
