Answer:
Each group will have 6 students, but there are less than 48 students in the class.
Now, if there are x teams, and each team has 6 students, the total number of students in teams will be x times 6, or:
x*6
And there are less than 48 students, then we x*6 will be smaller than 48, or:
x*6 < 48.
Now we can solve this inequality by dividing by 6 in both sides, this leads to:
x*6/6 < 48/6
x < 8
Then the total number of teams will be smaller than 8.
