Answer 1

$1) 2: frac{16}{5} = frac{2}{1} * frac{5}{16} = frac{5}{8} \ 2)3 frac{1}{4} - frac{2}{3} =2 frac{15}{12} - frac{8}{12} =2 frac{7}{12} \ 3) frac{31}{12} :3= frac{31}{36}\ 4)2 frac{5}{18} - frac{17}{36} =1 frac{46}{36} - frac{17}{36} =1 frac{29}{36} \ 5) frac{65}{36} : frac{65}{18} =frac{65}{36} *frac{18}{65} = frac{1}{2} \ 6) frac{5}{8} + frac{31}{36} =frac{45}{72} + frac{62}{72} = frac{107}{72}$
$7) frac{107}{72} -frac{1}{2} =frac{107}{72} -frac{36}{72} = frac{71}{72}$
