Решение:
- \[ \frac{3.6}{5.9 - 1.1} = \frac{3.6}{4.8} = \frac{36}{48} = \frac{3}{4} = 0.75 \]
- \[ \frac{1.3 + 9.2}{1.5} = \frac{10.5}{1.5} = \frac{105}{15} = 7 \]
- \[ \frac{28}{17.5 - 0.5} = \frac{28}{17} = 1 \frac{11}{17} \]
- \[ \frac{5.6 - 0.7}{0.8} = \frac{4.9}{0.8} = \frac{49}{8} = 6 \frac{1}{8} = 6.125 \]
