Question

4 2/3-5/9*2 4/7/(2 1/7+1 2/3):5 +0,8*1,25=

Answer 1

$4 frac{2}{3} - frac{5}{9} *2 frac{4}{7}:(2 frac{1}{7} +1 frac{2}{3} ):5 +0,8*1,25=$$=4 frac{2}{3} - frac{5}{9} * frac{18}{7}:(2 frac{3}{21} +1 frac{14}{21} ):5 +1=4 frac{2}{3} - frac{5}{1} * frac{2}{7}:3frac{17}{21} :5 +1=$$=4 frac{2}{3} -frac{10}{7}*frac{21}{80} * frac{1}{5} +1=4 frac{2}{3} -frac{2}{1}*frac{3}{80} +1=4 frac{2}{3} -frac{3}{40} +1=5 frac{2}{3} -frac{3}{40}=$$=5 frac{80}{120} -frac{9}{120}=5 frac{71}{120}$
