96 students attend the Chess Club every Wednesday.
800 is 100% of the population. We simply multiply 12% to the population of 800 to get its value.
800 x 12% = 96 students
To check: divide 96 by 800 to get its percentage.
96 / 800 = 0.12 x 100% = 12%
96 students is equivalent to 12% of 800, the school's total population.
