a) \(1\frac{1}{3} = \frac{1 \cdot 3 + 1}{3} = \frac{4}{3}\)
б) \(3\frac{7}{10} = \frac{3 \cdot 10 + 7}{10} = \frac{37}{10}\)
в) \(18\frac{6}{7} = \frac{18 \cdot 7 + 6}{7} = \frac{126 + 6}{7} = \frac{132}{7}\)
г) \(11\frac{11}{30} = \frac{11 \cdot 30 + 11}{30} = \frac{330 + 11}{30} = \frac{341}{30}\)
д) \(8\frac{3}{10} = \frac{8 \cdot 10 + 3}{10} = \frac{80 + 3}{10} = \frac{83}{10}\).
