Answer

Find out the how many cookies will each student get.

To prove

As given

mr.chan made 252 cookies for the annual fifth grade class bake sale .

they sold $\frac{3}{4}$ of them

Than

$Number\ of\ cookies\ left = \frac{3\times 252}{4}$

= 189

Number of cookies left after sold = 252 - 189

= 63

$\frac{3}{9}$ of the remaining cookies were given to P.T.A members .

Than

$Number\ of\ cookies\ left\ when\ given\ to\ P.T.A\ members = \frac{3\times 63}{9}$

= 21

Number of cookies left after giving to P.T.A members = 63 - 21

= 42

As given

mr.chan allowed the 12 student helper to divide the cookies that are left equally.

$Each\ student\ get\ cookies =\frac{42}{12}$

= 3.5

Therefore the 3.5 cookies each student gets.
