Question

thực hiện phép tính 1 cách hợp lí

\(\frac{3}{29}-\frac{1}{5}.\frac{29}{3}\)

Answer 1

\(\frac{3}{29}-\frac{1}{5}.\frac{29}{3}=\frac{3}{29}-\frac{29}{15}=\frac{-362}{145}\)

Answer 2

3/29 - 1/5 . 29/3

= 3/29 . 29/3 - 1/5

= 1 - 1/5

= 5/5 - 1/5

= 4/5

Answer 3

3/29 - 1/5 . 29/3

= 3/29 . 29/3 - 1/5

= 1 - 1/5

= 4/5

Answer 4

\(\frac{3}{29}-\frac{1}{5}.\frac{29}{3}=\frac{3}{29}.\frac{29}{3}-\frac{1}{5}\)

                            \(=\frac{87}{87}-\frac{1}{5}\)

                            \(=1-\frac{1}{5}=\frac{4}{5}\)
