thực hiện phép tính 1/6-1/36 -3/15-(-3)/25 -11/12-(-1) -5/9-(-5)/12 -3/4-4/5

`1/6 - 1/36`

`= 6/36 - 1/36`

`= 5/36`

____________________

`-3/15 - (-3)/25`

`= - 1/5 + 3/25`

`= - 5/25 + 3/25`

`= - 2/25`

_____________________

`- 11/12 - (-1)`

`= - 11/12 + 1`

`= - 11/12 + 12/12`

`= 1/12`

______________________

`- 5/9 - (-5)/12`

`= - 5/9 + 5/12`

`= - 20/36 + 15/36`

`= - 5/36`

_______________________

`- 3/4 - 4/5`

`= - 15/20 - 16/20`

`= - 31/20`
