There are 12 third grade students and 15 4th grade students in the band they will travel to a concert in cars that can hold four students each which of these can be used to find out how many cards are needed to drive the students

Respuesta :

Answer:

#_cars = 7

Explanation:

For this exercise let's start by finding the total number of students

          #_students = 12 +15

          #_students = 27

Now we can use a direct proportion relationship or rule of three. If 4 students drive, how many cars for 27 students?

          #_cars = 27 (¼)

          #_cars = 6.75

the number of cars must be an integer therefore the correct answer is

         #_cars = 7
