Marie made 3 dozen cookes she needs to put them in equal group so that the number of groups is at least 4 but less than 10 what are all the possible equal but less size groups she can make

Marie can divide her cookies into groups of 9, 6, or 4

Step-by-step explanation:

Marie has made 3 dozen cookies = 3 x 12 = 36 cookies

To form equal groups, she needs the same number of cookies in each group.

We know she can divide them into groups from 4 to 9 groups.

To get equal groups, we look for factors of 36 from 4 to 9

For 4 groups, 36/4 = 9 cookies per group

For 6 groups, 36/6 = 6 cookies per group

For 9 groups, 36/9 = 4 cookies per group

She can therefore divide into groups of 9, 6, or 4.
