[tex]2 \frac{4}{5} \div \frac{84}{10} \times 4 \frac{4}{5} = \\ \frac{14}{5} \div \frac{84}{10} \times \frac{24}{5} = \\ \frac{14}{5} \times \frac{10}{84} \times \frac{24}{5} = \\ \frac{3.360}{2.100} = \frac{8}{5} = 1 \frac{3}{5} [/tex]

2 4\5 : 8,4 x 4 4\5 =
2 : (8,4 x 4)
1 : (8,4 x 2)
1 : (84/10 x 2)
1 : 168/10
= 10/168
= 5/84
