(5/8+2 17/24):2,5
___________________×0,5
(1,3+23/30+4/11)×110/401

Answer 1

$\frac{(\frac{5}{8} +2\frac{17}{24}):2.5 }{(1.3+\frac{23}{30} +\frac{4}{11} )*\frac{110}{401} } *0.5=\frac{(\frac{5}{8}+\frac{65}{24} ):\frac{25}{10} }{(\frac{13}{10} +\frac{23}{30} +\frac{4}{11} )*\frac{110}{401} } *\frac{1}{2} =\frac{(\frac{15}{24}+\frac{65}{24} ):\frac{5}{2} }{(\frac{429}{330} +\frac{253}{330} +\frac{120}{330} )*\frac{110}{401} } *\frac{1}{2}=\frac{\frac{80}{24}*\frac{2}{5} }{\frac{802}{330}*\frac{110}{401} }*\frac{1}{2} =$

$=\frac{\frac{16}{12} }{\frac{2}{3} } *\frac{1}{2} =\frac{16}{12} *\frac{3}{2} *\frac{1}{2} =\frac{8}{4} *\frac{1}{2} =\frac{4}{4} =1$
