Question

2/9:(-0,2)+4/7*9-5/2)

Answer 1

$\frac{2}{9}:(-0,2)+ \frac{4}{7}*9- \frac{5}{2}= \\ \\ \frac{2}{9}:(- \frac{2}{10})+ \frac{4*9}{7}- \frac{5}{2}= \\ \\ \frac{2}{9}:(- \frac{2}{10})+ \frac{36}{7}- \frac{5}{2}= \\ \\- \frac{10}{9}+ \frac{36}{7}- \frac{5}{2}= \frac{-140+648-315}{126} = \boxed{ \frac{503}{126}}$
