If the teacher graded 75% of the tests, and this amounted to 15 papers, we can set up the following equation to find the total number of students in the class (let's denote the total number of students as \( x \)):
\[
0.75x = 15
\]
To solve for \( x \), we can divide both sides by 0.75:
\[
x = \frac{15}{0.75}
\]
Calculating the right side:
\[
x = 20
\]
Thus, the total number of students in the class is **20**.
\[
0.75x = 15
\]
To solve for \( x \), we can divide both sides by 0.75:
\[
x = \frac{15}{0.75}
\]
Calculating the right side:
\[
x = 20
\]
Thus, the total number of students in the class is **20**.
