Math HESI A2 Practice Test - Nurselytic

Correct Answer: A

Rationale:
To calculate 54% of $789.56, you multiply 0.54 by 789.56, which equals $426.36.
Therefore, choice A, $426.36, is the correct answer.
Choice B, $426.37, is incorrect as it is a slightly higher value.
Choice C, $363.20, is incorrect as it is significantly lower than the correct answer.
Choice D, $526.38, is incorrect as it is higher than the correct calculation result.

Correct Answer: A

Rationale:
To convert a fraction to a decimal, divide the numerator by the denominator. In this case, 3 divided by 4 is equal to 0.75.
Therefore, the correct answer is A.

Choices B, C, and D are incorrect because they do not represent the equivalent decimal value of 3/4. 0.5 is the decimal equivalent of 1/2, 0.65 is the decimal equivalent of 13/20, and 0.85 is the decimal equivalent of 17/20.

Correct Answer: D

Rationale:
To convert kilograms to grams, you multiply by 1,000 since there are 1,000 grams in a kilogram.
Therefore, 8 kilograms = 8 x 1,000 = 8,000 grams. The correct answer is 8,000 grams, which is option D.

Choices A and C are incorrect as they incorrectly multiply by 10,000 instead of 1,000.
Choice B is incorrect as it divides 8 by 10 instead of multiplying by 1,000.

Correct Answer: B

Rationale: The correct answer is B: 5.73. When dividing 3.44 by 0.6, the calculation is 3.44 · 0.6 = 5.73.
Choice A (11.41) is incorrect because it is the result of multiplying, not dividing.
Choice C (2.33) and
Choice D (0.57) are also incorrect results obtained by incorrect calculations.

Correct Answer: A

Rationale: The correct answer is A: 10,000 grams. There are 1,000 grams in a kilogram.
Therefore, to find the number of grams in 10 kilograms, you multiply 10 (kilograms) by 1,000 (grams/kilogram) to get 10,000 grams.
Choice B (100 grams) is incorrect as it represents the conversion for 1 kilogram, not 10 kilograms.
Choice C (1000 grams) is incorrect as it is equal to 1 kilogram, not 10 kilograms.
Choice D (100,000 grams) is incorrect as it represents the conversion for 100 kilograms, not 10 kilograms.
