2¹/₂ cookies
Given:
Question:
How many cookies will each student get?
The Process:
Step-1
Mrs. Diaz makes 5 dozen cookies for her class.
[tex]\boxed{ \ 1 \ dozen = 12 \ units \ }[/tex]
[tex]\boxed{ \ 5 \ dozen = ? \ units \ }[/tex]
[tex]\boxed{ \ 5 \times 12 = 60 \ cookies \ }[/tex]
Step-2
One-ninth of her 27 students are absent the day she brings the cookies.
[tex]\boxed{ \ \frac{1}{9} \times 27 \ students = 3 \students \ are \ absent \ }[/tex]
In diagram, [tex]Total \ students: \boxed{3}\boxed{3}\boxed{3}\boxed{3}\boxed{3}\boxed{3}\boxed{3}\boxed{3}\boxed{3} = 27[/tex]
3 students are absent, that is [tex]\boxed{3}[/tex]
So, the number of students present is 27 - 3 = 24 students, or [tex]\boxed{3}\boxed{3}\boxed{3}\boxed{3}\boxed{3}\boxed{3}\boxed{3}\boxed{3} = 24[/tex]
Step-3
And now, let's find out how many cookies will each student get.
[tex]\boxed{ \ 24 \ students = 60 \ cookies \ }[/tex]
[tex]\boxed{ \ 1 \ students = \ ? \ cookies \ }[/tex]
[tex]\boxed{ \ 60 \div 24 = \frac{60}{24} \ }[/tex]
[tex]\boxed{ \ 60 \div 24 = \frac{60 \div 12}{24 \div 12} \ }[/tex]
[tex]\boxed{ \ 60 \div 24 = \frac{5}{2} \ }[/tex]
Thus, each student get [tex]\boxed{\boxed{ \ \frac{5}{2} \ or \ 2\frac{1}{2} \ cookies \ }}[/tex]
