Question

4/11 x -2/9 + 4/11 x -8/9 + 4/11 x 1/9=??? tính dùm em nha

Answer 1

Ta có : \(\frac{4}{11}.\frac{-2}{9}+\frac{4}{11}\frac{-8}{9}+\frac{4}{11}.\frac{1}{9}\)

= \(\frac{4}{11}.\left(\frac{-2}{9}+\frac{-8}{9}+\frac{1}{9}\right)\)

= \(\frac{4}{11}.\frac{-9}{9}\)

= \(\frac{4}{11}.\left(-1\right)\)

= \(\frac{-4}{11}\)

Answer 2

\(\frac{4}{11}\left(-\frac{2}{9}+-\frac{8}{9}+\frac{1}{9}\right)=\frac{4}{11}1=\frac{4}{11}\)
