A class voted for either rollerblading, swimming, or biking as their favorite summer activity. If rollerblading got 27% percent of the vote and swimming got 33%, what percentage of the class voted for biking?
All you have to do is find the rest of the percentage. Percentage adds up to 100%. So you will have to add the two percentages they gave you. 27+33=60%. Now you have to take away 60 from 100. 100-60=40%.
