Реши примеры с дробями из 6 варианта: 1) 2/3 + 1/2

Привет! Конечно, я помогу тебе решить эти примеры. 1) $\frac{2}{3} + \frac{1}{2} = \frac{4}{6} + \frac{3}{6} = \frac{7}{6} = 1\frac{1}{6}$ 2) $6 - \frac{1}{10} = \frac{60}{10} - \frac{1}{10} = \frac{59}{10} = 5\frac{9}{10}$ 3) $3\frac{7}{15} + 8\frac{3}{4} = 3\frac{28}{60} + 8\frac{45}{60} = 11\frac{73}{60} = 12\frac{13}{60}$ 4) $2\frac{19}{36} - \frac{7}{9} = 2\frac{19}{36} - \frac{28}{36} = 1\frac{55}{36} - \frac{28}{36} = 1\frac{27}{36} = 1\frac{3}{4}$ 5) $\frac{5}{12} \times \frac{4}{5} = \frac{5 \times 4}{12 \times 5} = \frac{20}{60} = \frac{1}{3}$ 6) $4\frac{1}{3} \times \frac{3}{10} = \frac{13}{3} \times \frac{3}{10} = \frac{13 \times 3}{3 \times 10} = \frac{39}{30} = \frac{13}{10} = 1\frac{3}{10}$ 7) $\frac{1}{9} : \frac{1}{3} = \frac{1}{9} \times \frac{3}{1} = \frac{1 \times 3}{9 \times 1} = \frac{3}{9} = \frac{1}{3}$ 8) $2\frac{1}{5} : 11 = \frac{11}{5} : 11 = \frac{11}{5} \times \frac{1}{11} = \frac{11 \times 1}{5 \times 11} = \frac{11}{55} = \frac{1}{5}$
