Question

m=-1,2:(1/1/5.1,25)/0.64-1/25+(1,08-1/25):4/7/(5/5/9-9/4).36/17 +0,6.0.5;2/5

Answer 1

\(=-\dfrac{6}{5}:\left(\dfrac{6}{5}\cdot\dfrac{5}{4}\right):\dfrac{16}{25}-\dfrac{1}{25}+\left(1.04\right)\cdot\dfrac{4}{7}:\left(5:\dfrac{5}{9}-\dfrac{9}{4}\right)\cdot\dfrac{36}{17}+\dfrac{3}{10}\cdot\dfrac{5}{2}\)

\(=\dfrac{-6}{5}\cdot\dfrac{4}{6}\cdot\dfrac{25}{16}-\dfrac{1}{25}+\dfrac{1664}{8925}+\dfrac{3}{4}\)

\(=\dfrac{-27}{50}+\dfrac{1664}{8925}=-\dfrac{6311}{17850}\)
