HESI A2 Practice Test Math

Correct Answer: A

Rationale: To find the number of plots, divide the total land by the size of each plot: 56 acres ÷ 0.25 acres/plot = 224 plots (Option A). This is correct as it follows the basic concept of division. Option B, C, and D are incorrect as they do not result from the correct division calculation.

Correct Answer: C

Rationale: To calculate 0.9 divided by 3, we divide 0.9 by 3, which equals 0.3. This is the correct answer (C) because dividing 0.9 by 3 results in 0.3. Option A (0) is incorrect as the division does not equal 0. Option B (3) is incorrect as the result is not equal to 3. Option D (9) is incorrect as the division does not equal 9. Therefore, the correct answer is C (0.3).

Correct Answer: A

Rationale: To convert fluid ounces to gallons, we know that 1 gallon equals 128 fluid ounces. Therefore, to find how many gallons are in 576 fluid ounces, we divide 576 by 128, which equals 4. So, the correct answer is A: 4 gallons. Option B (5 gallons) is incorrect because the conversion calculation shows that 576 fluid ounces is equivalent to 4 gallons, not 5 gallons. Option C (6 gallons) is incorrect as well, as 576 fluid ounces is less than 6 gallons. Option D (3 gallons) is incorrect because the conversion calculation clearly demonstrates that 576 fluid ounces is equal to 4 gallons, not 3 gallons.

Correct Answer: A

Rationale: To solve for x in the equation X/4 = 9/x, we can cross multiply to get X * x = 4 * 9. Simplifying further, we get x^2 = 36, so x = √36 = 6. Choice A (x = 6) is correct. Choices B, C, and D are incorrect because they do not satisfy the equation when substituted back in. B: 6/4 ≠ 9/6, C: 6/4 ≠ 9/9, D: 6/4 ≠ 9/2.

Correct Answer: A

Rationale: To convert a decimal to a percent, you multiply by 100. In this case, 0.98 * 100 = 98%. Therefore, the correct answer is A. Choice B is incorrect as it represents 9%, not 0.98%. Choice C is incorrect as it is the decimal form itself, not the percentage. Choice D is incorrect as it represents 99%, not 0.98%.
