There are 47 students taking a field trip. The students are being driven in cars, to a play, by adult volunteers. Each driver can take at most 4 students. How many cars are needed for the field trip? Will each car have 4 students?
47/ 4 = 11 r 3 so 12 cars are needed.
12 cars are needed for the field trip and one car will have 3 students.
Write all the equations that have 12 as the missing factor.
