The percentage of people with a dog is `(129/300)*100 = 43%`
The percentage of people that own a cat is 34%. Using this and the percentage of people that own a dog, the percentage of people that own neither of the two is 100% - 77% = 23%, this is equivalent to 69 people.
The most popular pet is a dog as 43% have a dog, 34% have a cat, 17% have a gerbil and 6% don't have a pet.
The number of people with a dog is greater than the number of people with a cat, which is the second most popular pet, by 27.
129 / 300 would equal your percentage of responses owning a dog. (So 43%).
Add together the % of people surveyed who own a cat and the % of those who own a dog (.34 + .43 = .77) then take that away from 100% (1 - .77 = .23) for the percentage of people who do not own a cat or dog. (So 23%)
With 129 responses, the dog is the leading pet above cats (102 responses) by 27 responses gerbils (51 responses) by 78 responses, and no pet (18 responses) by 111 responses.
