Question

How do you simplify `5/6 + 2/3 - 4/9`?

Answer 1

`=color(blue)(19/18`

Explanation:

`5/6 +2/3-4/9`

We first need to take the L.C.M of the denominators:
L.C.M`(6,3,9) = 18`

`5/6 +2/3-4/9= (5*3)/(6*3) +(2*6)/(3*6)-(4*2)/(9*2`

`=15/18 +12/18 - 8/18`

`=(15+12-8)/18`

`=color(blue)(19/18`
