Ответ:

1. 5 \(\frac{7}{10}\) = 4 + 1 \(\frac{7}{10}\) = 4 + \(\frac{10}{10}\) + \(\frac{7}{10}\) = 4 \(\frac{10 + 7}{10}\) = 4 \(\frac{17}{10}\)
2. 3 \(\frac{2}{3}\) = 2 + 1 \(\frac{2}{3}\) = 2 + \(\frac{3}{3}\) + \(\frac{2}{3}\) = 2 \(\frac{3 + 2}{3}\) = 2 \(\frac{5}{3}\)
3. 8 \(\frac{10}{21}\) = 7 + 1 \(\frac{10}{21}\) = 7 + \(\frac{21}{21}\) + \(\frac{10}{21}\) = 7 \(\frac{21 + 10}{21}\) = 7 \(\frac{31}{21}\)
4. 11 \(\frac{1}{5}\) = 10 + 1 \(\frac{1}{5}\) = 10 + \(\frac{5}{5}\) + \(\frac{1}{5}\) = 10 \(\frac{5 + 1}{5}\) = 10 \(\frac{6}{5}\)
