Forty-four students go on a field trip. The students are divided into groups of 7 students. How many groups of 7 will there be?.
strojnjashka [21]

6

To solve this problem, you need to divide the total number of students going on the field trips with the number of students in each group.

44/7

= 6 R 2

Since, I assume there can <em>only</em> be groups of 7, the answer is 6.
