The equation is 45 ÷ x = 25% of 90. First, calculate 25% of 90: 0.25 × 90 = 22.5. So the equation becomes 45 ÷ x = 22.5. Solving for x gives x = 45 ÷ 22.5 = 2. Among the options given (5, 6, 7, 8), none is 2, so the correct answer should be 2, which is not listed. The originally given correct answer (B: 6) is incorrect for the equation as stated. Therefore, the correct answer is A: 5 is also incorrect, but since 2 is not an option, the closest correct answer is to fix the options or question. However, based on the equation and calculation, x = 2 is the correct solution. Since 2 is not an option, the question or options need correction. The verified correct answer is A: 5 is not correct, but among the given options, none is correct. The explanation is that the correct solution is x = 2.
