Answer:
9 students per team
Explanation:
There are a total of 180 students.
They want to divide it into 20 teams.
You can solve the rate by dividing the students by the number of teams.
180 ÷ 20 = 18 ÷ 2 = 9
Now you put the phrase "per __" next to the result to show the rate unit.
9 students per (one) team.
