HESI A2 Math Practice Exam

Correct Answer: B

Rationale: The correct answer is B: 1:00 AM. In military time, 0100 translates to 1:00 AM. When converting military time to standard time, you simply drop the leading zero and read the remaining numbers as a regular time. Choice A is incorrect because it is vague and not a specific time. Choice C is incorrect as 3:00 AM is not represented by 0100 in military time. Choice D is incorrect because 12:30 AM is not the equivalent of 0100 in military time.

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: To calculate the percentage increase, subtract the initial price ($9.00) from the final price ($10.00) to get the increase ($1.00). Then, divide the increase by the initial price ($1.00 / $9.00 = 0.1111). Convert the result to a percentage by multiplying by 100, giving 11.11%. Choice B (11.11%) is correct. Choice A (5%) is incorrect because the increase is $1.00, not $0.45. Choice C (20%) and Choice D (25%) are also incorrect as they do not accurately reflect the calculated percentage increase of 11.11%.

Correct Answer: A

Rationale: Certainly! To compare, we need to convert both fractions to a common denominator. LCM of 8 and 100 (8*25) is 100. Sally ate (5/8)*100 = 62.5%. John ate 75%. Clearly, 75% is more than 62.5%. So, John ate more. Other choices are incorrect as they do not consider the actual percentages consumed by Sally and John.
