• Find d.

Group

`(1)/(3)+d=(5)/(6)\\(1)/(3)+d-(1)/(3)=(5)/(6)-(1)/(3)\\d+(1)/(3)+(-1)/(3)=(5)/(6)-(1)/(3)\\d+(1-1)/(3)=(5)/(6)-(1)/(3)\\d+(0)/(3)=(5)/(6)-(1)/(3)\\d+0=(5)/(6)-(1)/(3)\\d=(5)/(6)-(1)/(3)\\d=(5)/(6)+(-1\cdot 2)/(3\cdot 2)\\d=(5)/(6)+(-1\cdot 2)/(6)\\d=(5)/(6)+(-2)/(6)\\d=(5-2)/(6)\\d=(3)/(6)\\d=(1\cdot 3)/(2\cdot 3)\\d=(1)/(2)`

Hope it helps.
