Smith chart application to a single stub tuner

1) A normalized load admittance of (0.2 + j0.2) needs a single stub tuner.
i) how far down the line should it be located?
ii) what is normalized admittance at the point just to right of where stub should be attached?

2) A certain point along a transmission line the normalized admittance is (1+j1.5)
i) Design the short-circuited stub necessary to change the normalized admittance to (1+j0)

Explain using a smith chart.
