Помогите пожалуйста решить сложение

1) $\frac{3}{1} + \frac{1}{7} = \frac{21}{7} + \frac{3}{7} = \frac{24}{7} = 3\frac{3}{7}$

НОЗ: 7

2) $6 + 5\frac{2}{9} = 11\frac{2}{9}$

3) $5 + 4\frac{9}{10} = 9\frac{9}{10} = 9,9$

4) $9\frac{13}{16} + 23 = 32\frac{13}{16} = 32,8125$

5) $4\frac{2}{6} + 2\frac{3}{6} = \frac{26}{6} + \frac{15}{6} = \frac{41}{6} = 6\frac{5}{6}$

6) $10\frac{9}{13} + 8\frac{3}{13} = \frac{139}{13} + \frac{107}{13} = \frac{246}{13} = 18\frac{12}{13}$

7) $6\frac{5}{16} + 2\frac{3}{16} = \frac{101}{16} + \frac{35}{16} = \frac{136}{16} = 8,5$

8) $2\frac{5}{22} + 8\frac{15}{22} = \frac{49}{22} + \frac{191}{22} = \frac{240}{22} = 10\frac{20}{22}$

9) $5\frac{29}{40} + 4\frac{31}{40} = \frac{229}{40} + \frac{191}{40} = \frac{420}{40} = 10,5$
