Answer 1

3¹/₂ or 3.5 cookies

Further explanation

Given:

• Mr. Chan made 252 cookies for the Annual Fifth Grade Class bake sale.
• They sold $\frac{3}{4}$ of them and $\frac{3}{9}$ of the remaining cookies were given to P.T.A members.
• Mr. Chan allowed the 12 student helper to divide the cookies that are left equally.

Question:

How many cookies will each student get?

The Process:

Step-1

$Let \ us \ prepare \boxed{252 \div 4 = 63}$

Then, let us create a suitable diagram as follows:  

$\boxed{63}\boxed{63}\boxed{63}\boxed{63} = 252 \ cookies}$  

So, 1 unit of diagram is equal to 63 cookies.

• Mr. Chan sold $\frac{3}{4}$ of them, that is $\boxed{ \ 3 \ units \times 63 \ cookies = 189 \ cookies \ sold \ }$
• The remaining cookies are $\boxed{ \ 252 - 189 = 63 \ cookies \ }$, or 1 unit left of the diagram above.

Step-2

$Let \ us \ prepare \boxed{63 \div 9 = 7}$

Then, let us create a suitable diagram as follows:  

$\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7} = 63 \ cookies}$  

So, 1 unit of diagram is equal to 7 cookies.

• Next, $\frac{3}{9}$ of the remaining cookies were given to P.T.A. members, that is $\boxed{ \ 3 \ units \times 7 \ cookies = 21 \ cookies \ }$.
• The last number of cookies remaining was $\boxed{ \ 6 \ units \times 7 \ cookies = 42 \ cookies \ }$ or $\boxed{ \ 63 - 21 = 42 \ cookies \ }$.

Step-3

Mr. Chan allowed the 12 student helper to divide the cookies that are left equally.

Let us calculate how many cookies will each student get.

$\boxed{ \ 42 \ cookies \div 12 \ students \ }$

$\boxed{ \ = \frac{42}{12} \ }$

The numerator and denominator are equally divided by 6.

$\boxed{ \ = \frac{42 \div 6}{12 \div 6} \ }$

$\boxed{ \ = \frac{7}{2} \ }$

$\boxed{ \ = \frac{6}{2} + \frac{1}{2} \ }$

$\boxed{\boxed{ \ = 3\frac{1}{2} \ }}$

Thus, each student will get $3\frac{1}{2}$ cookies.

Answer 2

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.
