20% of the 520 students in Wendover Middle
School were involved in school sports. Of those
students, 12.5% were on the wrestling team. How
many students were on the wrestling team?

13 students.

Step-by-step explanation:

20% of 520 students =(20/100)*520=104 students

now,

12.5% of 20% of 520 students = (12.5/100)*((20/100)*520)

                                                  = (12.5/100)*104

                                                  = 13 students
