Answer:
The fraction that eats in the cafeteria is 2/3
Explanation:
To find this, start by taking the number of students and subtracting the amount that bring their lunch.
18 - 6 = 12 that eat in the cafeteria.
Now that we have that number, divide by the total number of students.
12/18
To simplify this fraction, divide both numbers by 6.
2/3
