1) \(\frac{11}{20} = \frac{11 \cdot 5}{20 \cdot 5} = \frac{55}{100} = 0,55\)
2) \(\frac{7}{8} = \frac{7 \cdot 125}{8 \cdot 125} = \frac{875}{1000} = 0,875\)
3) \(\frac{17}{16} = \frac{17}{2^{4}} = \frac{17 \cdot 5^{4}}{2^{4} \cdot 5^{4}} = \frac{17 \cdot 625}{10^{4}} = \frac{10625}{10000} = 1,0625\)
Ответ: 1) 0,55; 2) 0,875; 3) 1,0625
