216. Выделите целую часть: а) из дробей \(\frac{56}{17}\), \(\frac{355}{27}\), \(\frac{154}{11}\); б) из дробной части чисел \(3\frac{19}{10}\); \(5\frac{38}{15}\); \(4\frac{72}{7}\); \(2\frac{36}{12}\).

а) \(\frac{56}{17}\), \(\frac{355}{27}\), \(\frac{154}{11}\)

$$\frac{56}{17} = 3\frac{5}{17}$$ $$\frac{355}{27} = 13\frac{4}{27}$$ $$\frac{154}{11} = 14$$

б) \(3\frac{19}{10}\); \(5\frac{38}{15}\); \(4\frac{72}{7}\); \(2\frac{36}{12}\)

$$3\frac{19}{10} = 3 + \frac{19}{10} = 3 + 1\frac{9}{10} = 4\frac{9}{10}$$ $$5\frac{38}{15} = 5 + \frac{38}{15} = 5 + 2\frac{8}{15} = 7\frac{8}{15}$$ $$4\frac{72}{7} = 4 + \frac{72}{7} = 4 + 10\frac{2}{7} = 14\frac{2}{7}$$ $$2\frac{36}{12} = 2 + \frac{36}{12} = 2 + 3 = 5$$
