Привет! Давай решим примеры с дробями по порядку. 1) $\frac{5}{6} + \frac{4}{6} = \frac{9}{6} = 1\frac{3}{6} = 1\frac{1}{2}$ 2) $\frac{1}{7} + \frac{3}{49} = \frac{7}{49} + \frac{3}{49} = \frac{10}{49}$ 3) $\frac{17}{26} - \frac{8}{26} = \frac{9}{26}$ 4) $\frac{11}{24} - \frac{1}{12} = \frac{11}{24} - \frac{2}{24} = \frac{9}{24} = \frac{3}{8}$ 5) $\frac{8}{49} \cdot \frac{7}{64} = \frac{8}{49} \cdot \frac{7}{64} = \frac{1}{7} \cdot \frac{1}{8} = \frac{1}{56}$ 6) $\frac{5}{20} : \frac{5}{4} = \frac{1}{4} \cdot \frac{4}{5} = \frac{1}{5}$ 7) $1\frac{2}{7} + 5\frac{1}{7} = 6\frac{3}{7}$ 8) $6\frac{1}{3} - \frac{5}{6} = 6\frac{2}{6} - \frac{5}{6} = 5\frac{8}{6} - \frac{5}{6} = 5\frac{3}{6} = 5\frac{1}{2}$ 9) $4 - 1\frac{1}{2} = 3\frac{2}{2} - 1\frac{1}{2} = 2\frac{1}{2}$ 10) $3\frac{8}{11} \cdot 1\frac{3}{41} = \frac{41}{11} \cdot \frac{44}{41} = \frac{44}{11} = 4$ 11) $7\frac{1}{2} : 7\frac{2}{4} = \frac{15}{2} : \frac{30}{4} = \frac{15}{2} \cdot \frac{4}{30} = \frac{60}{60} = 1$ 12) $2\frac{2}{5} : 6 = \frac{12}{5} : 6 = \frac{12}{5} \cdot \frac{1}{6} = \frac{2}{5}$
