Ответ:

здравствуйте!

$(1 \frac{1}{5} + 2 \frac{3}{10}) \div \frac{1}{2} + (6 \frac{3}{4} - 2 \frac{2}{3}) \div 1 \frac{1}{6} = \\ = ( \frac{6}{5} + \frac{23}{10}) \times 2 + ( \frac{27}{4} - \frac{8}{3}) \times \frac{6}{7} = \\ = \frac{35}{10} \times 2 + \frac{49}{12} \times \frac{6}{7} = 7 + \frac{7}{2} = \\ = \frac{14 + 7}{2} = \frac{21}{2}$= 10,5

Answer 2

(6/5 + 23/10) * 2 + (27/4 - 8/3) / 7/6 =

35/10 * 2 + (81/12 - 32/12) / 7/6 =

35/5 + 49/12 * 6/7 = 7 + 7/2 = 10,5. Либо 10 1/2
