Заполним таблицу:
| a | $$\frac{13}{32}$$ | $$\frac{22}{125}$$ | $$\frac{27}{44}$$ | $$\frac{14}{17}$$ |
| b | $$\frac{9}{32}$$ | $$\frac{3}{47}$$ | $$\frac{27}{44}$$ | $$\frac{22}{123}$$ |
| a + b | $$\frac{13}{32} + \frac{9}{32} = \frac{22}{32} = \frac{11}{16}$$ | $$\frac{22}{125} + \frac{3}{47} = \frac{22 \cdot 47 + 3 \cdot 125}{125 \cdot 47} = \frac{1034 + 375}{5875} = \frac{1409}{5875}$$ | $$\frac{27}{44} + \frac{27}{44} = \frac{54}{44} = \frac{27}{22} = 1 \frac{5}{22}$$ | $$\frac{14}{17} + \frac{22}{123} = \frac{14 \cdot 123 + 22 \cdot 17}{17 \cdot 123} = \frac{1722 + 374}{2091} = \frac{2096}{2091} = 1 \frac{5}{2091}$$ |
| a - b | $$\frac{13}{32} - \frac{9}{32} = \frac{4}{32} = \frac{1}{8}$$ | $$\frac{22}{125} - \frac{3}{47} = \frac{22 \cdot 47 - 3 \cdot 125}{125 \cdot 47} = \frac{1034 - 375}{5875} = \frac{659}{5875}$$ | $$\frac{27}{44} - \frac{27}{44} = 0$$ | $$\frac{14}{17} - \frac{22}{123} = \frac{14 \cdot 123 - 22 \cdot 17}{17 \cdot 123} = \frac{1722 - 374}{2091} = \frac{1348}{2091}$$ |
