Пошаговое объяснение:

[tex]1) 5\frac{1}{25} *7,125=5,04*7,125=35,91 \\ 2)35,91+5,04 = 40,95\\ 3)40,95:9,1= 4,5\\ 4)4,5*\frac{8}{27} = \frac{45}{10} *\frac{8}{27} =\frac{20}{15} =\frac{4}{3} \\\\ 5)1\frac{3}{5} :1,5=\frac{8}{5} :\frac{15}{10} =\frac{8}{5} *\frac{2}{3} =\frac{16}{15} =1 \frac{1}{15} \\ 6)2 - 1\frac{1}{15}=\frac{14}{15}\\ \\[/tex]

[tex]7)\frac{4}{3} :\frac{14}{15} =\frac{4}{3}*\frac{15}{14}=\frac{10}{7} \\ \\ 8)\frac{10}{7} *\frac{8}{15}=\frac{16}{21} \\ 9)0,2+\frac{16}{21} =\frac{1}{5} +\frac{16}{21} =\frac{21+80}{105} =\frac{101}{105} \\ \\ otvet:\frac{101}{105}[/tex]
