The phrase is “ n students into groups of 6” Think about what makes sense. Separating n students into 6 equal groups means dividing n students into 6 equal groups. So, write a division expression. & separated \ \underline{n \ students} \ Division is not commutative. The order in which we divide numbers matters. So, while n \div 6 represents the number of students in each group, n \div 6 does not. The answer is n \div 6 .
