6 ц. 7/9 + 5/9 - (453 - 45)/900               24            61/9 + 5/9 - 34/75          24

 

                                                      *               =                                     *         

 

7/9 + (546 - 54)/900 + 1/50                    43          7/9 + 41/75 + 1/50           43

 

 

172/25       24        3096       24      1728

              *         =             *         =           

121/90       43         605        43      605

Answer 2

$frac{{6,(7)+frac{5}{9}-0,45(3)}}{frac{7}{9}+0,54(6)+0,02}*frac{24}{43}= frac{frac{61}{9}+frac{5}{9}-frac{136}{300}}{frac{7}{9}+frac{164}{300}+frac{2}{100}}*frac{24}{43}=$

=$frac{6600-408}{700+510}*frac{24}{43}=frac{144*12}{605}=frac{1728}{605}approx2,86.$
