(3 целых 1/2 - 7/9) • 6/11+(8/33-1/11):10/11= ?

Answer 1

$(3 frac{1}{2} - frac{7}{9} ) * frac{6}{11} +( frac{8}{33}- frac{1}{11}): frac{10}{11} \ 1),3 frac{1}{2} - frac{7}{9}= frac{7}{2} - frac{7}{9}= frac{7*9-7*2}{18}= frac{63-14}{18} = frac{49}{18} \ 2), frac{8}{33}- frac{1}{11}= frac{8-1*3}{33} = frac{5}{33} \ 3), frac{49}{18} * frac{6}{11} = frac{49*6}{18*11} = frac{49}{3*11} =frac{49}{33} \ 4), frac{5}{33} : frac{10}{11} =frac{4}{33}* frac{11}{10}=frac{5*11}{33*10}=frac{1}{3*2}=frac{1}{6}$
$5), frac{49}{33} + frac{1}{6} = frac{49}{3*11} + frac{1}{3*2} = frac{49*2+1*11}{3*2*11} = frac{109}{3*2*11} = frac{109}{66} =1frac{43}{66}$
