HESI A2 Math Practice Test 2023

Correct Answer: A

Rationale: To subtract 32 divided by 8\9, first divide 32 by 8 to get 4. Then divide 4 by 9, which equals 4\9. Subtracting 4\9 from 32 gives 36, which is the correct answer (A). Choice B (32) is incorrect as it only divides 32 by 8, not considering the second division by 9. Choices C (40) and D (44) are incorrect as they do not follow the correct division and subtraction steps.

Correct Answer: C

Rationale: To solve for x, we first cross multiply: x*500 = 250*3. Simplifying gives x = 750/500 = 1.5. Choice C is correct. Choice A (150) and D (60) are incorrect as they are not the solutions to the equation. Choice B (25.5) is incorrect as it does not match the result of the calculation.

Correct Answer: D

Rationale: To find 70% of 200, you multiply 200 by 0.70 (70%). So, 200 x 0.70 = 140. Therefore, the correct answer is D (140). Choice A (100) and B (100) are incorrect as they do not represent 70% of 200. Choice C (200) is incorrect as it represents the full 100% of 200, not 70%.

Correct Answer: A

Rationale: To add fractions with different denominators, first find a common denominator. In this case, the least common multiple of 8, 10, and 5 is 40. Then, convert each fraction to have a denominator of 40: 7/8 = 35/40, 9/10 = 36/40, and 6/5 = 24/40. Add them up to get 95/40 which simplifies to 2 & 15/40 = 3 & 3/8 = 3 & 39/40 (Choice A). Other choices are incorrect because they do not represent the correct sum of the fractions.

Correct Answer: A

Rationale: The correct answer is A: 1/6. The probability of getting a 1 on a six-sided die is calculated by dividing the number of favorable outcomes (rolling a 1) by the total number of possible outcomes (6 sides on the die). Since there is only 1 side with a 1, the probability is 1/6. Choice B (1/4) is incorrect as it represents the probability of rolling a 1 on a four-sided die, which only has 4 sides. Choice C (1/3) is incorrect as it represents the probability of rolling a 1 on a three-sided die, which is not a standard die. Choice D (1/2) is incorrect as it represents the probability of rolling a 1 on a two-sided die, which is not a standard die.
