There are 12 students in Mr. Smith's class and 10 students in Mrs. Jacob's class.
Given:
There were 4 students absent in each class on Monday.
Question:
How many students are in each class?
The Process:
Part-1: in Mr. Smith's class
The diagram representing all students in the class is as follows:
[tex]\boxed{\cdot} \boxed{\cdot} \boxed{\cdot}[/tex]
[tex]\frac{1}{3}[/tex] were absent on Monday, that is [tex]\boxed{\cdot}[/tex] or 1 of 3 units.
There were 4 students absent on Monday.
Let us count how many students are in Mr. Smith's class.
[tex]\boxed{ \ 1 \ unit = 4 \ students \ }[/tex]
[tex]\boxed{ \ 3 \ unit = \ ? \ students \ }[/tex]
[tex]\boxed{ \ 3 \times 4 = 12 \ students \ }[/tex]
Thus, there are 12 students in Mr. Smith's class.
Part-2: in Mrs. Jacob's class
The diagram representing all students in the class is as follows:
[tex]\boxed{\cdot} \boxed{\cdot} \boxed{\cdot} \boxed{\cdot} \boxed{\cdot}[/tex]
[tex]\frac{2}{5}[/tex] were absent on Monday, that is [tex]\boxed{\cdot} \boxed{\cdot}[/tex] or 2 of 5 units.
There were 4 students absent on Monday.
[tex]\boxed{ \ 2 \ unit = 4 \ students \ }[/tex]
[tex]\boxed{ \ 1 \ unit = \ ? \ students \ }[/tex]
[tex]\boxed{ \ 4 \div 2 = 2 \ }[/tex]
Therefore, [tex]\boxed{ \ 1 \ unit = 2 \ students \ }[/tex]
Let us count how many students are in Mrs. Jacob's class.
[tex]\boxed{ \ 1 \ unit = 2 \ students \ }[/tex]
[tex]\boxed{ \ 5 \ unit = \ ? \ students \ }[/tex]
[tex]\boxed{ \ 5 \times 2 = 10 \ students \ }[/tex]
Thus, there are 10 students in Mrs. Jacob's class.
