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
How many grams are in 10 kilograms?
Correct Answer: A
Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in 1 kilogram. So, to find the number of grams in 10 kilograms: 10 kilograms x 1000 = 10,000 grams. Therefore, the correct answer is A: 10,000 grams. The other choices are incorrect because they do not correctly convert 10 kilograms to grams. B: 100 grams is too small, C: 1000 grams is equivalent to 1 kilogram, and D: 100,000 grams is too large.
Question 3 of 5
A nurse works in the military hospital from 1300 to 2000. How many hours does this nurse work?
Correct Answer: C
Rationale: The nurse works from 1300 to 2000, which translates to 1 PM to 8 PM. To calculate the hours worked, subtract the start time from the end time: 8 PM - 1 PM = 7 hours. Therefore, the correct answer is C (7 hours). Choice A (8 hours) is incorrect as it includes the end time, Choice B (11 hours) is incorrect as it adds extra hours, and Choice D (12 hours) is incorrect as it adds both the start and end times.
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 pizza has a diameter of 40cm. What is its perimeter (circumference)?
Correct Answer: C
Rationale: To find the perimeter (circumference) of a circle, we use the formula C = πd, where d is the diameter. Given the diameter of the pizza is 40cm, we substitute this into the formula: C = π * 40 = 125.6cm (Choice C). This is the correct answer as it accurately calculates the circumference. Choices A, B, and D are incorrect because they do not provide the correct calculation based on the given diameter. Choice A (62.8cm) seems to be using the formula for the circumference of a circle with radius, not diameter. Choices B and D are simply incorrect calculations.
