HESI A2 Math Practice Test 2024

Correct Answer: A

Rationale: To determine the patient with the highest systolic pressure in the table, you need to find the largest number in the 'systolic pressure' column. This is because the highest systolic pressure reading directly corresponds to the individual with the highest blood pressure value among all age groups. Comparing means (Choice B) would not identify the specific individual with the highest pressure, as it calculates an average. Adding all values and dividing by the total number (Choice C) would give the average pressure, not the highest. Subtracting the lowest from the highest (Choice D) would only give the range, not the specific highest value.

Correct Answer: B

Rationale: To change a percentage to a decimal, you divide by 100. In this case, 0.03% divided by 100 equals 0.0003. Therefore, the correct answer is B. Choice A (0.03) is the original percentage value without conversion. Choice C (0.3) is 10 times the correct answer. Choice D (0.003) is 10 times smaller than the correct answer.

Correct Answer: D

Rationale: To find 25% of 400, you multiply 400 by 0.25 (25% as a decimal). So, 400 * 0.25 = 100. Therefore, the correct answer is D. Choice A (800) is incorrect as it is 200% of 400. Choice B (10,000) is incorrect as it is 2500% of 400. Choice C (200) is incorrect as it is 50% of 400.

Correct Answer: A

Rationale: To convert a decimal to a percent, you multiply by 100. In this case, 0.09 * 100 = 9%. Therefore, the correct answer is A: 9%. Choice B (90%) is incorrect as it would be the result of multiplying by 1000, not 100. Choice C (1%) is incorrect as it would be the result of moving the decimal point two places to the right without multiplying by 100. Choice D (0%) is incorrect as the number is not zero, it's 0.09.

Correct Answer: A

Rationale: To convert centimeters to inches, we use the conversion factor 1 inch = 2.54 centimeters. Therefore, to convert 65.4 centimeters to inches, we divide 65.4 by 2.54. The calculation is 65.4 / 2.54 = 25.74 inches. This is why choice A (25.74) is correct. Choices B, C, and D are incorrect as they do not correctly convert centimeters to inches.
