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 .
