Question

Помогите пожалуйста

Answer 1

$3frac{1}{7} times frac{3}{11} + frac{3}{8} div frac{7}{12} = frac{22}{7} times frac{3}{11} + frac{3}{8} times frac{12}{7} = frac{6}{7} + frac{9}{14} = frac{12 + 9}{14} = frac{21}{14} = frac{3}{2} = 1.5$

$4 frac{1}{12} - 3 frac{7}{8} + 3 frac{11}{18} div frac{13}{18} = frac{49}{12} - frac{31}{8} + frac{65}{18} times frac{18}{13} = frac{98 - 93}{24} + 5 = 5 frac{5}{24}$

$4 frac{1}{6} + (2 frac{3}{4} - 2 frac{1}{6} ) div 2 frac{4}{5} - 1 frac{3}{8} = frac{25}{6} + ( frac{11}{4} - frac{13}{6}) div frac{14}{5} - frac{11}{8} = frac{25}{6} + frac{33 - 26}{12} div frac{14}{5} - frac{11}{8} = frac{25}{6} + frac{7}{12} times frac{5}{14} - frac{11}{8} = frac{25}{6} + frac{5}{24} - frac{11}{8} = frac{100 + 5 - 33}{24} = frac{72}{24} = 3$

$(2 frac{1}{2} - frac{3}{5} times 2 frac{1}{2} ) div frac{7}{10} + 1 frac{5}{6} = ( frac{5}{2} - frac{3}{5} times frac{5}{2}) div frac{7}{10} + frac{11}{6} = ( frac{5}{2} - frac{3}{2} ) div frac{7}{10} + frac{11}{6} = frac{2}{2} times frac{10}{7} + frac{11}{6} = frac{60 + 77}{42} = frac{137}{42} = 3 frac{11}{42}$
