Question

total student#=28
shoe # | student # | %
1-5 | 11 | $\frac{11}{28}=39%$
6-10 | |
11-15 | |
16-20 | |

Explanation:

Assuming we need to fill the table (for example, if we assume equal distribution or other scenarios, but since no other info is given, maybe a common case: let's say we want to find student # for 6 - 10, 11 - 15, 16 - 20 with remaining students. Total students = 28, already 11 in 1 - 5, so remaining = 28 - 11 = 17. Let's split evenly or as per a pattern, but maybe the problem is to calculate percentage or student #. Wait, the given is 1 - 5 has 11 students, 39% (11/28). Let's say we need to find for other ranges. But since the problem isn't clear, maybe the initial calculation is shown. Wait, the user might want to know how the percentage is calculated. Let's do that.

Step1: Identify total and part

Total students $n = 28$, students in 1 - 5 $x = 11$.

Step2: Calculate percentage

Percentage $= \frac{x}{n} \times 100 = \frac{11}{28} \times 100 \approx 39\%$ (as shown).

Answer:

The percentage is calculated as $\frac{11}{28} \times 100 \approx 39\%$ (for 1 - 5 shoe size range).
