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?

Answer :

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.
