Answer:
<h2>Ms. Morris has to form 5-students groups.</h2>
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
![\frac{25}{3}\approx 8.33](https://tex.z-dn.net/?f=%5Cfrac%7B25%7D%7B3%7D%5Capprox%208.33)
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
![\frac{25}{4} = 6.25](https://tex.z-dn.net/?f=%5Cfrac%7B25%7D%7B4%7D%20%3D%206.25)
The same reason here, she cannot divide a students in parts to have equal groups.
Therefore, she has to make 5-students groups, because
![\frac{25}{5}=5](https://tex.z-dn.net/?f=%5Cfrac%7B25%7D%7B5%7D%3D5)
Which means she can make groups of 5 students each, and she would have equal groups.
