№833Заранее спасибо !!!

1) $4 + \frac{4}{5} = \frac{5*4+4}{5} = \frac{24}{5}$

2) $5+ 8 / \frac{24}{5} =5+ 8 * \frac{5}{24} =5+ \frac{5}{3} = \frac{3*5+5}{3} = \frac{20}{3}$

3) $6+5/ \frac{20}{3} =6+5* \frac{3}{20} =6+ \frac{3}{4} = \frac{4*6+3}{4} = \frac{27}{4}$

4) $7+9/ \frac{27}{4} =7+9* \frac{4}{27} =7+ \frac{4}{3} = \frac{3*7+4}{3} = \frac{25}{3}$

5) $5/ \frac{25}{3} =5* \frac{3}{25} = \frac{3}{5}$
