108 students
Given:
In the fifth grade at Lenape Elementary School,
Question:
How many students are in the grade?
The Process:
Let us prepare a model for students who wear glasses.
[tex]\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot} = 60[/tex]
Then we make a model for students who do not wear glasses. As we know above, there are ⁴/₅ as many students who do not wear glasses as those who do wear glasses.
[tex]\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot} = ?[/tex]
Let us calculate the number of students who do not wear glasses.
[tex]\boxed{ \ = \frac{4}{5} \times 60 \ }[/tex]
We crossed out 5 and 60.
[tex]\boxed{ \ = 4 \times 12 \ }[/tex]
[tex]\boxed{\boxed{ \ 48 \ }}[/tex]
Finally, let's add up the number of students who wear glasses and do not wear glasses to find out how many students are in the grade.
[tex]\boxed{\boxed{ \ 60 + 48 = 108 \ students \ }}[/tex]
