HESI A2 Math Practice Exam

Correct Answer: D

Rationale: To find what percent of 36 is 9, we divide 9 by 36: 9/36 = 0.25. To convert this decimal to a percentage, we multiply by 100: 0.25 x 100 = 25%. So, the correct answer is D (10%). Choice A (25%), B (20%), and C (15%) are incorrect as they do not correctly represent the relationship between 9 and 36.

Correct Answer: A

Rationale: To convert 0.007 kilograms to grams, you should multiply by 1000 since there are 1000 grams in a kilogram. So, 0.007 kg * 1000 = 7 grams (Option A). Option B is incorrect as it incorrectly multiplies by 10 instead of 1000. Option C and D mistakenly move the decimal point to the wrong place.

Correct Answer: B

Rationale: The correct answer is B: MCMVI. Here's the rationale: 1. M represents 1000, CM represents 900, and VI represents 6. 2. Combining these symbols, MCMVI represents 1000 (M) + 900 (CM) + 6 (VI) = 1906. 3. Option A (MCMIV) is incorrect as IV represents 4, not 6. 4. Option C (MDCCCCVI) is incorrect as it uses the subtractive notation excessively (900 + 100 + 100 + 100 + 100 + 5 + 1). 5. Option D (MCMVII) is incorrect as VII represents 7, not 6.

Correct Answer: C

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: B

Rationale: To convert inches to feet, divide the number of inches by 12 since there are 12 inches in a foot. 72 inches divided by 12 equals 6 feet. Therefore, the correct answer is B: 6 feet. Choice A (12 feet) is incorrect as it is the conversion of 144 inches, not 72 inches. Choice C (4 feet) and Choice D (17 feet) are also incorrect as they do not accurately represent the conversion of 72 inches to feet.
