What should be subtracted from `(-3)/4`so as to get `5/6?`

Explanation

Let the value be ` x` that is subtracted from `-3/4` so as we get `5/6`.
`=>-3/4-x=5/6`
`=>-x=5/6+3/4`
Taking `24` as LCM of `6` and `4`.
`=>-x=(5×4+3×6)/(24)`
`=>-x=(20+18)/(24)`
`=>-x=38/24`
`=>-x=19/12`
`=>x=-19/12`
Therefore, `-19/12` should be subracted from `-3/4` so as to get `5/6`.
