The sixth-graders at Simon's school got to choose between a field trip to a museum and a field trip to a factory. 18 sixth-graders picked the museum and 42 sixth-graders picked the factory. What percentage of the sixth-graders picked the museum?
18+42=60 60 is our 100% A equation can be used to find this; 60=100% 18 = x% We want to know what percentage 18 sixth graders is of 60. 18*100=1,800 1800/60=30 So 30% is the answer.
