Можешь выполнить действия в задании 4?

Конечно, давай решим эти примеры вместе! 4 а) $3 \frac{3}{6} + 5 \frac{2}{7} = 3 \frac{1}{2} + 5 \frac{2}{7} = \frac{7}{2} + \frac{37}{7} = \frac{49}{14} + \frac{74}{14} = \frac{123}{14} = 8 \frac{11}{14}$ 4 б) $5 \frac{1}{6} + 4 \frac{2}{4} = 5 \frac{1}{6} + 4 \frac{1}{2} = \frac{31}{6} + \frac{9}{2} = \frac{31}{6} + \frac{27}{6} = \frac{58}{6} = 9 \frac{4}{6} = 9 \frac{2}{3}$ 4 в) $8 \frac{7}{8} - 6 \frac{5}{6} = \frac{71}{8} - \frac{41}{6} = \frac{213}{24} - \frac{164}{24} = \frac{49}{24} = 2 \frac{1}{24}$ 4 г) $\frac{3}{10} - \frac{4}{15} = \frac{9}{30} - \frac{8}{30} = \frac{1}{30}$ 4 д) $1 \frac{2}{3} + 6 \frac{5}{6} = \frac{5}{3} + \frac{41}{6} = \frac{10}{6} + \frac{41}{6} = \frac{51}{6} = 8 \frac{3}{6} = 8 \frac{1}{2}$ 4 e) $5 - 3 \frac{2}{7} = 5 - \frac{23}{7} = \frac{35}{7} - \frac{23}{7} = \frac{12}{7} = 1 \frac{5}{7}$ 4 ж) $4 \frac{3}{8} = \frac{35}{8}$ 4 з) $5 \frac{9}{10} : \frac{6}{10} = \frac{59}{10} : \frac{6}{10} = \frac{59}{10} * \frac{10}{6} = \frac{59}{6} = 9 \frac{5}{6}$ 4 и) $1 \frac{1}{9} : 1 \frac{1}{2} = \frac{10}{9} : \frac{3}{2} = \frac{10}{9} * \frac{2}{3} = \frac{20}{27}$ 4 к) $2 \frac{6}{7} : 1 \frac{2}{3} = \frac{20}{7} : \frac{5}{3} = \frac{20}{7} * \frac{3}{5} = \frac{4}{7} * \frac{3}{1} = \frac{12}{7} = 1 \frac{5}{7}$ 4 л) $6 \frac{3}{5} * 10 = \frac{33}{5} * 10 = \frac{33}{1} * 2 = 66$ 4 м) $3 \frac{2}{3} : 6 \frac{1}{6} = \frac{11}{3} : \frac{37}{6} = \frac{11}{3} * \frac{6}{37} = \frac{11}{1} * \frac{2}{37} = \frac{22}{37}$
