boa noite !!!!

$( \frac{2}{5} ) \times \frac{3}{2} \times ( \frac{ - 15}{9} ) \times ( - 7) \\ \\ \frac{2}{5} \times \frac{3}{2} \times \frac{15}{9} \times 7 \\ \\ \frac{1}{5} \times 3 \times \frac{15}{9} \times 7 \\ \\ 3 \times \frac{3}{9} \times 7 \\ \\ \frac{3}{3} \times 7 \\ \\ = 7$

espero que eu tenha conseguido te ajudar...
