Math HESI A2 Practice Test Questions
Question 1 of 5
Convert 1/5 to a decimal.
Correct Answer: B
Rationale: To convert 1/5 to a decimal, you divide 1 by 5. This gives you 0.2, which is the correct answer (B). Choice A (0.5) is the decimal equivalent of 1/2, not 1/5. Choice C (1.5) is the sum of 1 and 1/2. Choice D (0.15) is the decimal equivalent of 15/100, not 1/5. Therefore, the correct answer is B (0.2).
Question 2 of 5
A patient's temperature is measured as 38.5 degrees Celsius. What is their temperature in Fahrenheit?
Correct Answer: D
Rationale: To convert Celsius to Fahrenheit, you use the formula: Fahrenheit = (Celsius x 1.8) + 32. Given the patient's temperature is 38.5 degrees Celsius, Fahrenheit = (38.5 x 1.8) + 32 = 104.9 degrees Fahrenheit (Option D). Options A, B, and C are incorrect as they do not match the correct conversion using the formula.
Question 3 of 5
Convert 1/5 to a decimal.
Correct Answer: B
Rationale: To convert 1/5 to a decimal, you divide 1 by 5. This gives you 0.2, which is the correct answer (B). Choice A (0.5) is the decimal equivalent of 1/2, not 1/5. Choice C (1.5) is the sum of 1 and 1/2. Choice D (0.15) is the decimal equivalent of 15/100, not 1/5. Therefore, the correct answer is B (0.2).
Question 4 of 5
How many milligrams are in 7 grams?
Correct Answer: A
Rationale: To convert grams to milligrams, you multiply by 1000 since there are 1000 milligrams in a gram. So, 7 grams x 1000 = 7000 mg. Therefore, the correct answer is A: 7000 mg. Option B (7 mg) is incorrect because it represents the original unit (grams). Option C (700 mg) is incorrect as it is a partial conversion error. Option D (70 mg) is incorrect as it is a multiple of 10 error.
Question 5 of 5
A farmer has 240 acres under cultivation at the cost of $188.99 per acre. If he averages a yield of 60 bushels per acre, what profit is expected if the price per bushel is $5.67?
Correct Answer: A
Rationale: To calculate the profit, we first find the total cost of cultivation: 240 acres * $188.99/acre = $45,357.60. Then, we find the total revenue from selling the yield: 240 acres * 60 bushels/acre * $5.67/bushel = $81,648. Finally, we subtract the cost from the revenue to get the profit: $81,648 - $45,357.60 = $36,290.40. Therefore, the correct answer is A. Choice B is incorrect because it miscalculates the profit by not subtracting the cost from the revenue. Choice C is incorrect as it overestimates the profit. Choice D is incorrect as it is not the accurate profit value based on the given information.
