First you need to find the amount of students who voted.
80 + 160 = 240
160 students out of 240 students who voted, voted for a bulldog. To find the percentage, you need to divide 160 by 240.
160/240 = .6 repeated
You need to move the decimal over two spaces to get the percentage. So then you have 66.6666%. Since it says to round to the nearest whole percent, you need to round the number right after the decimal. 6 rounds the number before it up so you get 67.
So the amount of students that voted for a bulldog is 67%.
