Question

4⅙*(1½–⅗)+(¾+⅚)*6
(6–2⅘)*3⅛–1⅗:¼

Answer 1

Ответ:

$4 \frac{1}{6} \times (1 \frac{1}{2} - \frac{3}{5} ) + ( \frac{3}{4} + \frac{5}{6} ) \times 6 \\ \frac{25}{6} \times ( \frac{3}{2} - \frac{3}{5} ) + \frac{19}{12} \times 6 \\ \frac{5}{2} \times \frac{3}{2} + \frac{19}{2} = \\ \frac{15}{4} + \frac{19}{2} = \frac{53}{4} = 13 \frac{1}{4}$

$(6 - 2 \frac{4}{5} ) \times 3 \frac{1}{8} - 1 \frac{3}{5} \div \frac{1}{4} \\ (6 - \frac{14}{5} ) \times 3 \times \frac{1}{8} - \frac{8}{5} \times 4 \\ \frac{16}{5} \times 3 \times \frac{1}{8} - \frac{32}{5} \\ \frac{2}{5} \times 3 - \frac{32}{5} = \frac{6}{5} - \frac{32}{5} = - \frac{26}{5} = - 5 \frac{1}{5}$
