Math HESI A2 Practice Test

Correct Answer: A

Rationale: To add 1/4 and 3/8, we need a common denominator, which is 8. So, 1/4 becomes 2/8. Adding 2/8 + 3/8 gives us 5/8. Therefore, the correct answer is A: 5/8. Choice B, 7/12, is incorrect as it is the result of adding 1/4 and 1/3. Choice C, 2/3, is incorrect as it is the result of adding 1/4 and 1/2. Choice D, 1/2, is incorrect as it is the result of adding 1/4 and 1/4.

Correct Answer: A

Rationale: To convert 5/8 to a decimal, divide 5 by 8, which equals 0.625. The correct answer is A (0.625) because it is the result of dividing the numerator by the denominator. Choice B (0.5) is incorrect as 5/8 is not equal to 0.5. Choice C (0.4) and choice D (0.75) are also incorrect as they do not represent the equivalent decimal value of 5/8.

Correct Answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000. Therefore, to find how many milliliters are in 6 liters, you would multiply 6 by 1000, which equals 6000 milliliters. Choice A (60 milliliters) is incorrect as it is 100 times less than the correct answer. Choice C (600 milliliters) is incorrect as it is 10 times less than the correct answer. Choice D (0.6 milliliters) is incorrect as it is a decimal and represents a fraction of the milliliters in 6 liters.

Correct Answer: A

Rationale: To subtract 12 - 7 4\5, you first convert 12 to an improper fraction: 12 = 60\5. Then, subtract 60\5 - 7 4\5 = 60\5 - 39\5 = 21\5. Finally, convert 21\5 back to a mixed number, which is 4 1\5 or 5 1\5. Therefore, the correct answer is A. Choices B, C, and D are incorrect as they do not result from the correct subtraction process.

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.
