The fist,second and third grade students went on a field trip.There were 227 third grade students and 262 fourth grade students.A total of 756 students went on the trip. How many first grade students went on the trip?

Respuesta :

267 first grade students went on the trip. (You’d do 227 + 262 you get 489 then you subtract that by the total number of students which is 756 and get 267)
