Answer:
Step-by-step explanation:
If Ms. Morris wants to divide all 25 students in 3, 4 or 5 equal teams, she to apply a division to know the number of students per group.
If she makes 3-students groups, it would be
[tex]\frac{25}{3}\approx 8.33[/tex]
Ms. Morris can't make 3-students groups, because she cant divide one student in parts to have equal groups.
If she considers 4-students groups, it would be
[tex]\frac{25}{4} = 6.25[/tex]
The same reason here, she cannot divide a students in parts to have equal groups.
Therefore, she has to make 5-students groups, because
[tex]\frac{25}{5}=5[/tex]
Which means she can make groups of 5 students each, and she would have equal groups.
