Question

( 3 - 2\9 )  nhân  ( 2-2\5)
 

Answer 1

\(\left(3-\frac{2}{9}\right)x\left(2-\frac{2}{5}\right)\)

\(=\left(\frac{27}{9}-\frac{2}{9}\right)x\left(\frac{10}{5}-\frac{2}{5}\right)\)

\(=\frac{25}{9}x\frac{8}{5}\)

\(=\frac{40}{9}\)

Answer 2

40/9 bạn nhé

Answer 3

\(\left(3-\frac{2}{9}\right)\cdot\left(2-\frac{2}{5}\right)\)

\(=\left(\frac{27}{9}-\frac{2}{9}\right)\cdot\left(\frac{10}{5}-\frac{2}{5}\right)\)

\(=\frac{25}{9}\cdot\frac{8}{5}\)

\(=\frac{25\cdot8}{9\cdot5}=\frac{5\cdot5\cdot8}{9\cdot5}=\frac{40}{9}\)
