Sally wants to divide the students in her class into grpups of no more than 4 students if there are 31 students in the class what is the least number of groups g into which the students can be divided?
7 because we will divide 31 ÷4
There are 32 students in a class how many ways can the class be divided in to groups with an equal number?
2 groups of 16, 4 groups of 8, 8 groups of 4, 16 groups of 2. Not really divided or in groups, but there could be 1 group of 32 or everyone by themselves.
Ms.Adams can divide all the students in her class into equal groups of 3 or equal groups of 5 what could be the total number of students in her class?
15 or any multiple of 15, including 15 trillion which is greater than the human popluation, but that is maths for you!
How do you solve this combinations problem .There are 20 students in one class. They need to form groups of at least 2 people and at most 4 people. In how many different ways can they do that?
There are only two possibilities... 10 groups of 2 or 5 groups of 4. Unless - you can have varying sized groups - which you didn't specify.

An algebra class of 21 students must send 5 students to meet with the principal How many different groups of 5 students could be formed from this class?
To find the number of different groups (a) within a larger group (b), use the formula b!/a!.(b-a)! where the ! sign indicates "factorial". In your problem b = 21 and a = 5 so we have 21!/(5!.16!) this simplifies to 21.20.19.18.17/5.4.3.2 cancelling leaves 21.19.3.17 ie 20349
How many ways can a group of 3 students be chosen from a class of 30 students?

they can be 2 groups of 16, 4 groups of 8, 8 groups of 4, or 16 groups of 2
