Question

Answer 1

\(10.-\dfrac{5}{9}+\dfrac{14}{18}-\dfrac{4}{9}+\dfrac{2}{9}+\dfrac{1}{2007}\)

\(=\left(-\dfrac{5}{9}-\dfrac{4}{9}\right)+\left(\dfrac{14}{18}+\dfrac{2}{9}\right)+\dfrac{1}{2007}\)

\(=-1+1+\dfrac{1}{2007}\)

\(=\dfrac{1}{2007}\)

Answer 2

10: \(=\dfrac{-5}{9}-\dfrac{4}{9}+\dfrac{2}{9}+\dfrac{7}{9}+\dfrac{1}{2007}=\dfrac{1}{2007}\)
