.066.... if x=0.0666

100x-10x=6.666-.666

90x=6

x=1/15  so it is rational  (as is any repeating numerical pattern)

...

16 can be expressed as 16/1 so it is rational...

...

√49=±7=±7/1, so it is rational

...

√17, seventeen is prime so the square root is irrational as it cannot be expressed as a ratio of two integers...

So only √17 is irrational from your list :)
