Answer 1

$1)- frac{3}{8} +3 frac{5}{9} =- frac{27}{72} +3 frac{40}{72} =3 frac{13}{72}$
$2)3 frac{13}{72} -0,1=3 frac{13}{72} - frac{1}{10} =3 frac{65}{360} - frac{36}{360} =3 frac{29}{360}$
=======================
2) 27,36-(-45,91)-(-14,09)-13,64=27,36+45,91+14,09-13,64=73,72
========================
3) $-3 frac{5}{8} -2 frac{7}{12} =-3 frac{15}{24} -2 frac{14}{24} =-5 frac{29}{24} =-6 frac{5}{24}$
