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
