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 [tex]\frac{3}{4}[/tex] of them
Than
[tex]Number\ of\ cookies\ left = \frac{3\times 252}{4}[/tex]
= 189
Number of cookies left after sold = 252 - 189
= 63
[tex]\frac{3}{9}[/tex] of the remaining cookies were given to P.T.A members .
Than
[tex]Number\ of\ cookies\ left\ when\ given\ to\ P.T.A\ members = \frac{3\times 63}{9}[/tex]
= 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.
[tex]Each\ student\ get\ cookies =\frac{42}{12}[/tex]
= 3.5
Therefore the 3.5 cookies each student gets.
3¹/₂ or 3.5 cookies
Further explanation
Given:
- Mr. Chan made 252 cookies for the Annual Fifth Grade Class bake sale.
- They sold [tex]\frac{3}{4}[/tex] of them and [tex]\frac{3}{9}[/tex] 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
[tex]Let \ us \ prepare \boxed{252 \div 4 = 63}[/tex]
Then, let us create a suitable diagram as follows:
[tex]\boxed{63}\boxed{63}\boxed{63}\boxed{63} = 252 \ cookies}[/tex]
So, 1 unit of diagram is equal to 63 cookies.
- Mr. Chan sold [tex]\frac{3}{4}[/tex] of them, that is [tex]\boxed{ \ 3 \ units \times 63 \ cookies = 189 \ cookies \ sold \ }[/tex]
- The remaining cookies are [tex]\boxed{ \ 252 - 189 = 63 \ cookies \ }[/tex], or 1 unit left of the diagram above.
Step-2
[tex]Let \ us \ prepare \boxed{63 \div 9 = 7}[/tex]
Then, let us create a suitable diagram as follows:
[tex]\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7} = 63 \ cookies}[/tex]
So, 1 unit of diagram is equal to 7 cookies.
- Next, [tex]\frac{3}{9}[/tex] of the remaining cookies were given to P.T.A. members, that is [tex]\boxed{ \ 3 \ units \times 7 \ cookies = 21 \ cookies \ }[/tex].
- The last number of cookies remaining was [tex]\boxed{ \ 6 \ units \times 7 \ cookies = 42 \ cookies \ }[/tex] or [tex]\boxed{ \ 63 - 21 = 42 \ cookies \ }[/tex].
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.
[tex]\boxed{ \ 42 \ cookies \div 12 \ students \ }[/tex]
[tex]\boxed{ \ = \frac{42}{12} \ }[/tex]
The numerator and denominator are equally divided by 6.
[tex]\boxed{ \ = \frac{42 \div 6}{12 \div 6} \ }[/tex]
[tex]\boxed{ \ = \frac{7}{2} \ }[/tex]
[tex]\boxed{ \ = \frac{6}{2} + \frac{1}{2} \ }[/tex]
[tex]\boxed{\boxed{ \ = 3\frac{1}{2} \ }}[/tex]
Thus, each student will get [tex]3\frac{1}{2}[/tex] cookies.
