Question

Answer 1

34%:\(\dfrac{51}{16}-3\dfrac{7}{9}.6,5-\left(0,4\right)^2\) 

\(=\dfrac{17}{50}:\dfrac{51}{16}-\dfrac{34}{9}.\dfrac{13}{2}-\dfrac{4}{25}\) 

\(=\dfrac{8}{75}-\dfrac{221}{9}-\dfrac{4}{25}\) 

\(=\left(\dfrac{8}{75}-\dfrac{4}{25}\right)-\dfrac{221}{9}\) 

\(=\dfrac{-4}{75}-\dfrac{221}{9}\) 

\(=\dfrac{-5537}{225}\)
