(4 5/12-3 7/18) /9,25+5/6 _________________________ (0,4+1/8+0,75)*2/3 если можно...

1) $4 \frac{5}{12} -3 \frac{7}{18} =1 \frac{15-14}{36} =1 \frac{1}{36}$

2) $1 \frac{1}{36} :9,25= \frac{37}{36} * \frac{4}{37} = \frac{1}{9}$

3) $\frac{1}{9}+ \frac{5}{6} = \frac{2+15}{18}= \frac{17}{18}$

4) $0,4+ \frac{1}{8} +0,75= \frac{2}{5} + \frac{1}{8} + \frac{3}{4} = \frac{16+5+30}{40} = \frac{51}{40}$

5) $\frac{51}{40} * \frac{2}{3} = \frac{17}{20}$

6) $\frac{17}{18} : \frac{17}{20} = \frac{17}{18} * \frac{20}{17} = \frac{10}{9} = 1\frac{1}{9}$

Ответ: $1 \frac{1}{9}$
