Calculate a percentage of a number.

A proportions question. Given the total number of impressions, and the number of impressions that were clicked, what percentage were clicked?

Given n = k%, what is 100%?

percentage rate is 0.5, 1, 1.5 or 2%. Number of impressions is randomised.

Given number of TARPs and total price, calculate the Cost per TARP.

Given potential audience, the percentage that view, and the percentage of these that click, calculate the CPA by dividing potential audience by clickers. 

All numbers randomised.
