Question

(\(\dfrac{9}{25}\)-2.18):(\(3\dfrac{4}{5}\)+0,2)

Answer 1

\(\left(\dfrac{9}{25}-2.18\right):\left(3\dfrac{4}{5}+0,2\right)=\left(\dfrac{9}{25}-36\right):\left(\dfrac{19}{5}+0,2\right)=-\dfrac{891}{25}:4=-\dfrac{891}{100}\)

Answer 2

`(9/25 - 2.18 ) : ( 3 4/5 + 0,2)`

`=(9/25 - 36):( 19/5 + 1/5)`

`=(9/25 - 900/25):4`

`=-891/25 : 4`

`=-891/25 . 1/4`

`=-891/100`

Answer 3

Ta có: \(\left(\dfrac{9}{25}-2\cdot18\right):\left(3+\dfrac{4}{5}+0.2\right)\)

\(=\left(\dfrac{9}{25}-36\right):4\)

\(=\dfrac{-891}{25}:4\)

\(=\dfrac{-891}{100}\)
