HESI A2 Practice Test Math

Correct Answer: A

Rationale: To find the number of candies each camper will receive, divide the total number of candies (225) by the number of campers (25). 225 ÷ 25 = 9. Therefore, each camper will receive 9 pieces of candy. Choice A is correct because it correctly calculates the equal distribution. Choices B, C, and D are incorrect as they do not divide the total number of candies by the number of campers to determine the equal distribution.

Correct Answer: A

Rationale: To convert a decimal to a percent, you multiply by 100. In this case, 0.98 * 100 = 98%. Therefore, the correct answer is A. Choice B is incorrect as it represents 9%, not 0.98%. Choice C is incorrect as it is the decimal form itself, not the percentage. Choice D is incorrect as it represents 99%, not 0.98%.

Correct Answer: A

Rationale: To find the full number, we can set up the equation: 0.30x = 18, where x is the full number. Solving for x, we get x = 18 / 0.30 = 60. Therefore, the correct answer is A (60). Choice B (30): 0.30 of 30 is 9, not 18. Choice C (40): 0.30 of 40 is 12, not 18. Choice D (45): 0.30 of 45 is 13.5, not 18.

Correct Answer: A

Rationale: To find the number of candies each camper will receive, divide the total number of candies (225) by the number of campers (25). 225 ÷ 25 = 9. Therefore, each camper will receive 9 pieces of candy. Choice A is correct because it correctly calculates the equal distribution. Choices B, C, and D are incorrect as they do not divide the total number of candies by the number of campers to determine the equal distribution.

Correct Answer: C

Rationale: The correct answer is C: 0.09%. To convert 0.0009 to a percentage, you move the decimal point two places to the right, resulting in 0.09%. Option A (0.009%) is incorrect as it would be the equivalent of 0.00009. Option B (0.9%) is incorrect as it represents 0.009. Option D (9%) is incorrect as it is equivalent to 0.09, which is 100 times greater than the given value.
