Divide each percentage by 100 to get a decimal ie. 41% is the same as .41. Then multiply 400 by each decimal to get the number of people that preferred each station. To get the ratio take the number of people that preferred WANR put a colon then the number of people who preferred WCLM. Then divided both by 8 which is the highest number that will go into both of them and you get 11:12.

# of people preferring WCLM = 24% or 24/100 x 4 = 96
so 96 people out of 400 preferred WCLM
# of people preferring WANR = 22% or 22/100 x 4 = 88 (out of 400)
ratio of WANR supporters to WCLM is 88:96 = 44:48 = 22:24 = 11:12 (simplified as far as possible)

To do this you must know the total number of people who were surveyed. For instance if 100 people were surveyed, 41 would be 41% and 22 would be 22%, etc. If 1000 people were interviewed, 41% would be 410 people and 22% would be 220 people, etc.
