4/9 x 13/3 - 4/3 x 40/9 

Ghi rõ cách giải

Answer 1

\(\frac{4}{9}\).\(\frac{13}{3}\)-\(\frac{4}{3}\).\(\frac{40}{9}\)=\(\frac{4.13}{9.3}\)-\(\frac{4.40}{3.9}\)

                                              =\(\frac{\left(4.13\right)-\left(4.40\right)}{9.3}\)

                                              = \(\frac{4\left(13-40\right)}{27}\)

                                              =\(\frac{4\left(-27\right)}{27}\)

                                              =-4

Answer 2

\(\frac{4}{9}\cdot\frac{13}{3}-\frac{4}{3}\cdot\frac{40}{9}\)

\(=\frac{4}{3}\cdot\frac{13}{9}-\frac{4}{3}\cdot\frac{40}{9}\)

\(=\frac{4}{3}\cdot\left(\frac{13}{9}-\frac{40}{9}\right)\)

\(=\frac{4}{3}\cdot-3=-4\)

Answer 3

=4/3 x 1/3 x 13/3 - 4/3 x 40/9

=4/3 x (1/3 x 13/3 - 40/9)

=4/3 x (-3)

=-4

Answer 4

Ta có : \(\frac{4}{9}.\frac{13}{3}-\frac{4}{3}.\frac{40}{9}\)

      \(=\frac{4}{9}.\frac{13}{3}-\frac{40}{3}.\frac{4}{9}\)

        \(=\frac{4}{9}.\left(\frac{13}{3}-\frac{40}{3}\right)\)

         \(=\frac{4}{9}.\left(-9\right)\)

          \(=\frac{4}{9}.\frac{-9}{1}\)

            \(=-4\)

Answer 5

\(\frac{4}{9}\)x\(\frac{13}{3}\)-\(\frac{4}{3}\)x\(\frac{40}{9}\)

=     \(\frac{52}{27}\)  -    \(\frac{160}{27}\)       

=             - 4  

Answer 6

Theo mình thì nên tính nhanh.

Answer 7

-4 đúng là chắc
