Answer 1

1)
$frac{5}{10} times frac{11}{3} + 17 frac{2}{10} = \ \ = frac{55}{30} + 17 frac{6}{30} = \ \ = 17 frac{61}{30} = 19 frac{1}{30}$

2)
$frac{97}{9} - frac{25}{10} times frac{7}{6} = frac{97}{9} - frac{175}{60} = \ \ = frac{1940}{180} - frac{525}{180} = frac{1415}{180} = frac{283}{36} = \ \ = 7 frac{31}{36}$

3)
$frac{17}{2} div frac{17}{3} + 19 frac{7}{10} = \ \ = frac{17}{2} times frac{3}{17} + 19 frac{7}{10} = \ \ = frac{3}{2} + 19 frac{7}{10} = frac{30}{20} + 19 frac{14}{20} = \ \ = 19 frac{44}{20} = 21 frac{1}{5} = 21.2$

4)
$frac{29}{4} times frac{35}{58} div frac{35}{6} = frac{29}{4} times frac{35}{58} times frac{6}{35} = \ \ = frac{3}{4} = 0.75$
