Calculate Student Height Percentages: Finding Statistics in a School of 160 Students

To solve this problem, we'll follow these steps:

• Step 1: Calculate the total number of students in the school.
• Step 2: Calculate the percentage of students who are taller than Silvana.

Now, let's work through each step:
Step 1: Silvana's school has 5 classes, each with 32 students. To find the total number of students, we multiply the number of classes by the number of students per class:
$5 \times 32 = 160 \text{ students}$.

Step 2: We know 40 students are taller than Silvana. We use the percentage formula to find the percentage of students taller than Silvana:
$\frac{40}{160} \times 100\% = 25\%$.

Therefore, the answer to Silvana's question is 25%.
