№4. а) Преобразуйте в смешанное число дробь: 1) \(\frac{15}{6}\) 2) \(\frac{39}{12}\) б) Преобразуйте в неправильную дробь смешанное число: 1) \(2\frac{5}{9}\) 2) \(3\frac{4}{16}\)

a) 1) \(\frac{15}{6}\) = 2 \(\frac{3}{6}\) = 2 \(\frac{1}{2}\) 2) \(\frac{39}{12}\) = 3 \(\frac{3}{12}\) = 3 \(\frac{1}{4}\) б) 1) \(2\frac{5}{9}\) = \(\frac{2 * 9 + 5}{9}\) = \(\frac{18 + 5}{9}\) = \(\frac{23}{9}\) 2) \(3\frac{4}{16}\) = \(\frac{3 * 16 + 4}{16}\) = \(\frac{48 + 4}{16}\) = \(\frac{52}{16}\) = \(\frac{13}{4}\) Ответ: a) 1) 2 \(\frac{1}{2}\), 2) 3 \(\frac{1}{4}\) б) 1) \(\frac{23}{9}\), 2) \(\frac{13}{4}\)
