Paul try to solve the value of \(\frac{x+y}{z}\) using a calculator.
He inputs \(x+y \div z\) and the result is \(12\).
For clarification, he inputs \(y+x \div z\) and the result is \(9\).
Lastly, Paul concludes that his input is wrong.
So, he input \((x+y) \div z\) and the result is \( 7\).
In the story, find the value of \(x+y+z\).

\[x=\dfrac{111110}{111111} , y = \dfrac{222221}{222223} , z = \dfrac{333331}{333334}\]
Compare \(x,y,z\).
