Question

tính

(8+\(2\dfrac{1}{3}\) - \(\dfrac{3}{5}\) ) -(5+0.4)- (\(\dfrac{10}{3}\) - 2)

Answer 1

`(8 + 2 1/3 - 3/5 )-( 5+0,4 )-(10/3 -2)`

`=(8 + 7/3 - 3/5)- ( 5+ 2/5 ) - ( 10/3-6/3)`

`= ( 24/3 + 7/3- 3/5)- ( 25/5 + 2/5) - 4/3`

`= ( 31/3 - 3/5 ) - 27/5 - 4/3`

`= 146/15 - 27/5 - 4/3`

`= 146/15 - 81/15 - 20/15`

`=( 146-81-20)/15`

`=45/15=3`
