Math HESI A2 Practice Test

Correct Answer: A

Rationale: To convert 3/4 to a decimal, divide 3 by 4. 3 ÷ 4 = 0.75, so the correct answer is A. Choice B (0.5) is incorrect because that's the decimal form of 1/2. Choice C (0.65) and D (0.85) are incorrect as they do not represent the fraction 3/4 accurately.

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: A

Rationale: To convert milliliters to liters, we divide by 1000 since 1 liter = 1000 milliliters. So, 2500 milliliters ÷ 1000 = 2.5 liters. Therefore, the correct answer is A: 2.5 liters. Explanation for other choices: B: 1.5 liters - Incorrect, obtained by incorrect division. C: 3.5 liters - Incorrect, obtained by adding instead of dividing. D: 0.25 liters - Incorrect, obtained by misplaced decimal point.

Correct Answer: B

Rationale: To change 0.26 to a fraction, we need to look at the decimal place. 0.26 can be written as 26/100, which can be simplified to 13/50 by dividing both the numerator and denominator by 2. This is the correct answer because it is in simplest form. Choice A is incorrect as 7/8 is not equivalent to 0.26. Choice C is incorrect as 26/100 is the initial form of 0.26, not simplified. Choice D is incorrect as 1/3 is not the equivalent fraction for 0.26.

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.
