HESI A2 Math Practice Test 2023 Questions
Question 1 of 5
Convert 7 grams to milligrams.
Correct Answer: B
Rationale: To convert grams to milligrams, you multiply by 1000 since there are 1000 milligrams in 1 gram. Therefore, 7 grams x 1000 = 7000 milligrams, which corresponds to choice B. Choice A is incorrect as it represents 700 mg (not 7000 mg). Choice C is incorrect as it represents 70 mg (not 7000 mg). Choice D is incorrect as it represents 0.007 mg (not 7000 mg).
Question 2 of 5
Change 0.004 to a ratio.
Correct Answer: A
Rationale: To change 0.004 to a ratio, we need to express it as a fraction. 0.004 as a fraction is 4/1000, which simplifies to 1/250. Therefore, the correct ratio is 1:250. Choice A is correct because it accurately represents the ratio of 0.004. Choices B, C, and D are incorrect because they do not accurately reflect the equivalent ratio for 0.004.
Question 3 of 5
What is the volume of a birthday party hat with a cone-shaped top having a radius of 5cm and a height of 12cm?
Correct Answer: C
Rationale: To find the volume of a cone, we use the formula V = (1/3)πr^2h. Plugging in the values, V = (1/3)π(5)^2(12) = 100π ≈ 314.16 cu cm. Therefore, the correct answer is C (150 cu cm), as it is the closest option to the calculated volume. Option A is too small, B is slightly larger, and D is too large compared to the actual volume.
Question 4 of 5
How many grams are in 6 kilograms?
Correct Answer: B
Rationale: To convert from kilograms to grams, you multiply by 1000 since 1 kilogram is equal to 1000 grams. So, 6 kilograms x 1000 = 6000 grams. Therefore, the correct answer is B: 6000 grams. Choice A (600 grams) is incorrect because it doesn't account for the conversion factor of 1000 between kilograms and grams. Choice C (600 grams) is also incorrect as it doesn't reflect the correct conversion. Choice D (60,000 grams) is incorrect as it misinterprets the conversion factor and multiplies incorrectly.
Question 5 of 5
Subtract 12 1/8 - 9 1/2.
Correct Answer: A
Rationale: To subtract mixed numbers, first convert them to improper fractions. 12 1/8 = 97/8 and 9 1/2 = 19/2. Then, subtract the fractions: 97/8 - 19/2 = 97/8 - 38/8 = 59/8. Finally, convert the result back to a mixed number: 59/8 = 7 3/8. Therefore, the correct answer is A: 2 5/8. Choices B, C, and D are incorrect because they do not match the result of the subtraction calculation.
