Question

(2/3-1/9): 5/6 <br />2 целых 7/8*5 целых 1/3: 3 целых 5/6<br />6 целых 2/3:(4/5-7/20)<br /><br />сколько будет 1/9÷5/6?

Answer 1

$( frac{2}{3}- frac{1}{9}): frac{5}{6}= frac{5}{9} * frac{6}{5}= frac{2}{3}$
$2 frac{7}{8} *5 frac{1}{3}:3 frac{5}{6}= frac{23}{8}* frac{16}{3}: frac{23}{6} = frac{23*2*6}{3*23} =4$
$6 frac{2}{3}( frac{4}{5}- frac{7}{20})= frac{20}{3}* frac{9}{20}=3$
$frac{1}{9}: frac{5}{6}= frac{1}{9}* frac{6}{5}= frac{2}{15}$
