Question

4 1/6 * (1 1/2 - 3/5) + (3/4 + 5/6)​

Answer 1

$4 frac{1}{6} * (1 frac{1}{2} - frac{3}{5}) + (frac{3}{4} + frac{5}{6}) = 4 frac{1}{6}(1 frac{1}{2} - frac{3}{5}) + frac{3}{4} + frac{5}{6} = 5 frac{1}{3}\\1) 1 frac{1}{2} - frac{3}{5} = 1 frac{5}{10} - frac{6}{10} = frac{9}{10}\\2) 4 frac{1}{6} * frac{9}{10} = frac{25}{6} * frac{9}{10} = frac{25*9}{6*10} = frac{5*3}{2*2} = frac{15}{4}\\3) frac{15}{4} + frac{3}{4} = frac{15+3}{4} = frac{18}{4}$

$4) frac{18}{4} + frac{5}{6} = frac{54}{12} + frac{10}{12} = frac{54+10}{12} = frac{64}{12} = frac{16}{3} = 5 frac{1}{3}$

Ответ: $5 frac{1}{3}$
