To find how many students are in the class, we can set up the equation based on the information provided.

We know that:

• 8 students play a sport.
• These 8 students represent 25% of the class.

Let $x$ represent the total number of students in the class. Since 25% of the class is equal to 8 students, we can write the equation as:

$\frac{25}{100} \times x = 8$

Simplify the fraction:

$0.25 \times x = 8$

Now, solve for $x$:

$x = \frac{8}{0.25}$

$x = 32$

So, there are 32 students in the class.

Would you like further details on the steps, or do you have any questions about the problem? Here are some related questions:

1. If 12 students in the class played a sport, what percentage would they represent?
2. If 40% of the class plays a sport, and there are 32 students, how many students play a sport?
3. How many students in a class of 40 would make up 25%?
4. If 50 students represent 25% of the class, what is the total class size?
5. If 60% of the class plays a sport, how many students are there in total if 12 students play?

Tip: To find percentages, always convert the percentage into a decimal (e.g., 25% becomes 0.25) before multiplying by the total quantity.
