Пожалуйста помогите!!!!!!!!!!!!!!!!!!!!!!!!!

Решите задачу:

$8.5 - \frac{1}{3} = \frac{17}{2} - \frac{1}{3} = 8 \frac{1}{6} \\ \\ 4 \frac{1}{9} + 1.8 = \frac{37}{9} + \frac{9}{5} = 5 \frac{41}{45} \\ \\ \frac{1}{9} \times 0.12 = \frac{1}{9} \times \frac{3}{25} = \frac{1}{3} \times \frac{1}{25} = \frac{1}{75} \\ \\ \frac{6}{7} \div 0.6 = \frac{6}{7} \div \frac{3}{5} = \frac{6}{7} \times \frac{5}{3} = \frac{2}{7} \times 5 = 1 \frac{3}{7}$
