Помогите пажалуйста

1 2/3-3,6):(-2 7/9 +4 1/5)*(-2,,6)-4,1

Answer 1

$(1 frac{2}{3} - 3.6) div ( - 2 frac{7}{9} + 4 frac{1}{5} ) times ( - 2.6) - 4.1 = \ = ( frac{5}{3} - frac{18}{5} ) div ( - frac{25}{9} + frac{21}{5} ) times ( - frac{13}{5} ) - frac{41}{10} = \ = ( frac{25}{15} - frac{54}{15} ) div ( - frac{125}{45} + frac{189}{45} ) times ( - frac{13}{5} ) - frac{41}{10} = \ = ( - frac{29}{15} ) div frac{64}{45 } times ( - frac{13}{5} ) - frac{41}{10} = \ = frac{29 times 45 times 13}{15 times 64 times 5} - frac{41}{10 } = frac{29 times 39}{320} - frac{41}{10} = \ = frac{29 times 39}{320} - frac{41 times 32}{320} = frac{1131 - 1312}{320} = frac{181}{320}$
