Ответ:
Используем правило \(a\frac{b}{c}=\frac{ac+b}{c}\).
- \(3\frac{1}{4}=\frac{3\cdot4+1}{4}=\frac{13}{4}\);
- \(4\frac{2}{8}=\frac{4\cdot8+2}{8}=\frac{34}{8}=\frac{17}{4}\);
- \(8\frac{1}{2}=\frac{8\cdot2+1}{2}=\frac{17}{2}\);
- \(5\frac{3}{7}=\frac{5\cdot7+3}{7}=\frac{38}{7}\);
- \(6\frac{1}{11}=\frac{6\cdot11+1}{11}=\frac{67}{11}\);
- \(7\frac{3}{8}=\frac{7\cdot8+3}{8}=\frac{59}{8}\);
- \(9\frac{5}{6}=\frac{9\cdot6+5}{6}=\frac{59}{6}\);
- \(12\frac{1}{3}=\frac{12\cdot3+1}{3}=\frac{37}{3}\);
- \(2\frac{4}{15}=\frac{2\cdot15+4}{15}=\frac{34}{15}\).
