Question

5. Mrs. Stauffer 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

well, Mrs Stauffer has 27 students total
she made 5 dozen cookies, or 5 * 12 = 60 cookies

she got to class, and low and behold, 1/9 of her students
are absent at the Justin Bieber concert

how many students are there anyway?

well, if 1/9 are absent, 8/9 are present then
how much is 8/9 of 27?


`\bf \cfrac{8}{9}\cdot 27` are present

keep in mind that 1/9 + 8/9 is 9/9 or 1 whole, thus 8/9 are there

now, Mrs Stauffer has 60 cookies to share among those, so
evenly that'd be
`\bf \cfrac{60}{(8)/(9)\cdot 27}`
