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