Question

Thực hiện phép tính :

\(\frac{-3}{11}:\frac{17}{15}+\frac{-3}{11}:\frac{17}{2}+\frac{8}{11}\)

Answer 1

\(\frac{-3}{11}:\frac{17}{15}+\frac{-3}{11}:\frac{17}{2}+\frac{8}{11}\)

\(=\frac{-3}{11}.\frac{15}{17}+\frac{-3}{11}.\frac{2}{17}+\frac{8}{11}\)

\(=\frac{-3}{11}.\left(\frac{15}{17}+\frac{2}{17}\right)+\frac{8}{11}\)

\(=\frac{-3}{11}.1+\frac{8}{11}\)

\(=\frac{-3}{11}+\frac{8}{11}\Rightarrow\frac{5}{11}\)

Answer 2

\(\frac{-3}{11}:\frac{17}{15}+\frac{-3}{11}:\frac{17}{2}+\frac{8}{11}\)

\(=\frac{-3}{11}.\left(\frac{15}{17}+\frac{2}{17}\right)+\frac{8}{11}\)

\(=\frac{-3}{11}.1+\frac{8}{11}\)

=\(\frac{-3}{11}+\frac{8}{11}\)

\(=\frac{5}{11}\)
