b) 40/15, 56/12, 42/9, 22/4, 50/6

Решение: \(\frac{40}{15} = \frac{8}{3} = 2\frac{2}{3}\) \(\frac{56}{12} = \frac{14}{3} = 4\frac{2}{3}\) \(\frac{42}{9} = \frac{14}{3} = 4\frac{2}{3}\) \(\frac{22}{4} = \frac{11}{2} = 5\frac{1}{2}\) \(\frac{50}{6} = \frac{25}{3} = 8\frac{1}{3}\) Ответ: \(2\frac{2}{3}, 4\frac{2}{3}, 4\frac{2}{3}, 5\frac{1}{2}, 8\frac{1}{3}\)
