HESI A2 Practice Test Math

Correct Answer: B

Rationale: To convert ounces to pints, we know that 1 pint is equal to 16 ounces. Therefore, to find how many pints are in 56 ounces, we divide 56 by 16, which equals 3.5 pints. Hence, the correct answer is B: 3.5 pints. A: 3 pints - Incorrect. 56 ounces is more than 3 pints. C: 7 pints - Incorrect. 56 ounces equals 3.5 pints, not 7 pints. D: 8 pints - Incorrect. 56 ounces is less than 8 pints.

Correct Answer: B

Rationale: To find x in the equation 40:5 = 60:x, we first simplify the left side to 8. Then, we set up the equation 8 = 60:x. To solve for x, we isolate x by multiplying both sides by x/60, resulting in x = 60/8 = 7. Choice B is correct. Choices A, C, and D are incorrect because they do not yield the correct value when substituted back into the equation.

Correct Answer: A

Rationale: To find the full number, we can set up the equation: 0.30x = 18, where x is the full number. Solving for x, we get x = 18 / 0.30 = 60. Therefore, the correct answer is A (60). Choice B (30): 0.30 of 30 is 9, not 18. Choice C (40): 0.30 of 40 is 12, not 18. Choice D (45): 0.30 of 45 is 13.5, not 18.

Correct Answer: A

Rationale: To find x, we need to set up a proportion: 15/x = 3/8. Cross multiply to get 15*8 = 3*x. Solving for x gives x=40. Choice A is correct because it correctly solves the proportion. Choices B, C, and D are incorrect as they do not yield the correct value of x when solving the proportion.

Correct Answer: A

Rationale: To find the total weight, multiply the number of boxes by the weight of each box. 36 boxes * 2.5 pounds = 90 pounds. Option A is correct because it correctly calculates the total weight. Option B (75 pounds) is incorrect as it doesn't account for all 36 boxes. Option C (120 pounds) is incorrect as it overestimates the weight. Option D (100 pounds) is incorrect as it underestimates the weight by not considering all boxes.
