Question

What number shoul be added to -5/6 to get 2/3​

Answer 1

Let it be x

ATQ

`\\ \sf\longmapsto x+(-5)/(6)=(2)/(3)`

`\\ \sf\longmapsto (6x-5)/(6)=(2)/(3)`

`\\ \sf\longmapsto 3(6x-5)=6(2)`

`\\ \sf\longmapsto 18x-15=12`

`\\ \sf\longmapsto 18x=12+15=27`

`\\ \sf\longmapsto x=(27)/(18)`

`\\ \sf\longmapsto x=(3)/(2)`
