Решение:
a) \( 3\frac{3}{4} = \frac{3 \cdot 4 + 3}{4} = \frac{12+3}{4} = \frac{15}{4} \)
б) \( 5\frac{5}{12} = \frac{5 \cdot 12 + 5}{12} = \frac{60+5}{12} = \frac{65}{12} \)
в) \( 10\frac{1}{9} = \frac{10 \cdot 9 + 1}{9} = \frac{90+1}{9} = \frac{91}{9} \)
г) \( 1\frac{1}{13} = \frac{1 \cdot 13 + 1}{13} = \frac{13+1}{13} = \frac{14}{13} \)
д) \( 1\frac{2}{13} = \frac{1 \cdot 13 + 2}{13} = \frac{13+2}{13} = \frac{15}{13} \)
е) \( 2\frac{22}{23} = \frac{2 \cdot 23 + 22}{23} = \frac{46+22}{23} = \frac{68}{23} \)
ж) \( 12\frac{1}{4} = \frac{12 \cdot 4 + 1}{4} = \frac{48+1}{4} = \frac{49}{4} \)
з) \( 3\frac{1}{3} = \frac{3 \cdot 3 + 1}{3} = \frac{9+1}{3} = \frac{10}{3} \)
и) \( 6\frac{6}{7} = \frac{6 \cdot 7 + 6}{7} = \frac{42+6}{7} = \frac{48}{7} \)
