HESI A2 Practice Test Math

Correct Answer: A

Rationale: To find x, first, find the ratio between the two parts of the equation: 7/5 = 91/x. Cross multiply to solve for x: 7x = 455. Divide by 7 to get x = 65 (Choice A). Choices B, C, and D are incorrect as they do not match the calculated value of x.

Correct Answer: A

Rationale: To convert ounces to milliliters, we use the conversion factor: 1 oz = 29.5735 mL. Since the bottle contains 1/2 oz, we multiply 1/2 by 29.5735 to get 14.78675 mL. Rounding up, the closest option is 15 mL (choice A). Choices B, C, and D are incorrect as they do not match the calculated conversion from ounces to milliliters.

Correct Answer: A

Rationale: To subtract mixed numbers, convert them to improper fractions. 3 4/5 = 19/5 and 7 7/10 = 77/10. Subtracting gives 19/5 - 77/10 = 38/10 - 77/10 = -39/10. Convert back to a mixed number: -39/10 = -3 9/10 (choice A). Other choices are incorrect as they do not match the correct result.

Correct Answer: A

Rationale: The correct answer is A: 579 copies. To find the number of copies each person made, divide the total number of copies (3,475) by the number of people who used the copier (6). 3,475 ÷ 6 = 579. Each person made 579 copies. Summary: - Choice B (680 copies) is incorrect because it does not evenly divide into the total number of copies. - Choice C (670 copies) is incorrect because it is not an even division of the total number of copies. - Choice D (585 copies) is incorrect because it is not the result of dividing the total number of copies by the number of people who used the copier.
