Question

Mrs. diaz makes 5 dozen cookies for her class. one ninth of her 27 students are absent the day she brings the cookies. if she shares the cookies equally among the students who are present, how many cookies will each student get

Answer 1

Each student gets 2.5 cookies.
We know that there are 24 students there and 60 cookies, (since one ninth of 27 is 3 so 3 students are not there, and 24 are, and that 5 dozen is another way to write 60) we need to divide 60 by 24 which is 2.5.

Answer 2

We know that Mrs. Diaz has a total of 60 cookies (which is 5 * 12 = 60).

To find how many students were absent, we divide the 27 by 1/9

To do this, we set the 27 into a fraction, which would be 27/1

Next we would flip the other fraction to be 1/27

Now we multiply.

27 * 1 and 9 * 1

27 / 9

When we simplify it, we get 3, which means 3 students were absent that day from Mrs. Diaz's class.

So, knowing that there are sixty cookies and 24 students, we divide.

60 / 24 = 2.5

Meaning that each student would get two cookies each, giving Mrs. Diaz 12 leftovers.
