Помогите пожалуйста в решении этих упражнений.

1. а)
$\frac{29}{6} = 4 \frac{5}{6}$
б)
$\frac{17}{8} = 2 \frac{1}{8} = 2.125$
в)
$\frac{40}{7} = 5 \frac{5}{7}$
2. а) , б)
$2 \frac{1}{3} = \frac{7}{3} \\ \\ 5 \frac{5}{6} = \frac{35}{6}$
в)
$6 \frac{7}{8} = \frac{55}{8}$
3. а), б), в)
$\frac{9}{12} = \frac{3}{4} = 0.75 \\ \frac{30}{42} = \frac{5}{7} \\ \frac{5}{90} = \frac{1}{18}$
4. а),б),в)
$\frac{4}{15} + \frac{3}{5} = \frac{4}{15} + \frac{9}{15} = \frac{13}{15} \\ 1 \frac{9}{14 } + 2 \frac{1}{7} = 1 \frac{9}{14} + 2 \frac{2}{14} = 3 \frac{11}{14} \\ 1\frac{5}{8} + 2 \frac{9}{16} = 1 \frac{10}{16} + 2 \frac{9}{16} = 3 \frac{19}{16} = 4 \frac{3}{16}$
5.
$\frac{7}{10} - \frac{5}{10} = 0.2 \\ \frac{38}{12} - \frac{25}{12} = 1 \frac{1}{12} \\ \frac{26}{16} - \frac{41}{16} = - \frac{25}{16} = - 1 \frac{9}{16}$
