Answer 1

1)$3,35-2 frac{13}{15} =3 frac{7}{20} -2 frac{13}{15} =3 frac{21}{60} -2 frac{52}{60} = frac{29}{60}$
2)$frac{29}{60} + frac{5}{8} = frac{58+75}{120} = frac{133}{120}$
3)$225:12,5=18$
4)$3 frac{14}{19} *2=7 frac{9}{19}$
5)$18-7 frac{9}{19} =10 frac{10}{19}$
6)$frac{133}{120} *10 frac{10}{19} = frac{133}{120} * frac{200}{19} = frac{35}{3}$
7)$24,57:3,5=7,02=7 frac{1}{50}$
8)$7 frac{1}{50} + frac{35}{3} =7 frac{1}{50} +11 frac{2}{3} =18 frac{3+100}{150} =18 frac{103}{150}$
