Analyze and solve the problem. 1. Joana has to split 24 pupils in her class into different groups with an equal number of pupils each. Not all of them can be in one group and each group has to have more than one pupil. In how many ways can she form these groups? 2. Delia has 112 red roses. Can she bundle it by 4 without a remainder? Is it possible also that she can bundle it by 8? How about 12?​
