HESI A2 Math Practice Test 2023

Correct Answer: B

Rationale: To find the perimeter of the table, we add the lengths of all four sides. Since opposite sides are equal, we have two pairs of sides with lengths 75cm and 50cm each. Therefore, the perimeter is 2(75cm) + 2(50cm) = 150cm. Choice A is incorrect because it only considers one pair of sides. Choice C is incorrect as it adds all sides together without considering the pairs. Choice D is incorrect as it only considers one side length.

Correct Answer: A

Rationale: To convert milliliters to liters, we need to divide by 1000 since there are 1000 milliliters in a liter. So, 300 milliliters ÷ 1000 = 0.3 liters. Therefore, the correct answer is A: 0.3 liters. Explanation for other choices: B: 3 liters - Incorrect, as 300 milliliters is not equal to 3 liters. C: 0.03 liters - Incorrect, the decimal point placement is off. D: 3.3 liters - Incorrect, as it is not the correct conversion from milliliters to liters.

Correct Answer: B

Rationale: To subtract 14.5 - 7.25, align the decimals and perform subtraction. Starting from the right, subtract 5 from 0 (borrow 1 from 4), giving 5. Then, subtract 2 from 4, giving 2. The correct answer is 7.25. Other choices are incorrect because they do not match the result obtained from the subtraction process. Choice A and C are too small, while choice D is too large.

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.

Correct Answer: C

Rationale: To convert 9/10 to a decimal, you divide 9 by 10. The result is 0.9. This is because in decimal form, the denominator becomes the place value. So 9 divided by 10 equals 0.9. Choice A (0.7) is incorrect because 7/10 is equivalent to 0.7. Choice B (0.8) is incorrect because 8/10 is equivalent to 0.8. Choice D (1) is incorrect as 1 represents the whole number equivalent, not the decimal form of 9/10. Therefore, the correct answer is C (0.9).
