24 is 32% of 75. The answer can be found by setting up a proportion: n/75 is set equal to 32/100, where x represents 32% of 75. By using cross multiplying and solving for the variable "n" we can determine that n = 24. Therefore, the equation n = 0.32(75) could be used to determine the correct answer. The formula n = 75 ÷ 0.32 is incorrect.
