It says to dilute each by a factor of 10. Are you asking for the calculations on how to dilute by a factor of 10?
If so, you simply take 1 ml of each and dilute to a final volume of 10 mls. Or take 10 mls and dilute to a final volume of 100 mls, etc.
If you're asking about calculations of the resulting pH, that's a much different story and you should re-post the question making that clear.
