HESI A2 Math Practice Test 2024

Correct Answer: A

Rationale: To solve 5 1/3 + 3 1/2, first convert mixed numbers to improper fractions: 5 1/3 = 16/3 and 3 1/2 = 7/2. Then, add the fractions: 16/3 + 7/2 = (32+21)/6 = 53/6. Convert the result back to a mixed number: 53/6 = 8 5/6, which is choice A. Choices B, C, and D are incorrect as they do not represent the correct sum of the given mixed numbers.

Correct Answer: C

Rationale: To convert scientific notation (4.82 x 10^3) to standard form, we multiply the coefficient (4.82) by 10 raised to the exponent (3). This gives us 4.82 x 1000 = 4820. Therefore, the value of the number in standard form is 4820. Explanation of incorrect choices: A: 0.00482 - This choice is incorrect because it represents a smaller value than the original number. B: 0.482 - This choice is incorrect as it is also smaller than the original number. D: 4820000 - This choice is incorrect as it represents a larger value than the original number.

Correct Answer: A

Rationale: To solve 7 1/8 + 2 4/12, first convert 2 4/12 to an improper fraction: 2 4/12 = 2 + 1/3 = 2 1/3 = 7/3. Now, add 7 1/8 and 7/3 by finding a common denominator, which is 24. 7 1/8 = 57/8. Add 57/8 and 7/3 to get 183/24. Simplify 183/24 to 9 11/24, which is the correct answer (A). Choices B, C, D are incorrect as they do not match the calculated result.

Correct Answer: A

Rationale: To find the correct answer, we need to set up a proportion: 4 cups of sugar for 120 cookies is equivalent to x cups of sugar for 90 cookies. Cross multiply to get 4*90 = 120*x, which simplifies to 360 = 120x. Divide by 120 to get x = 3 cups. Therefore, the correct answer is A: 3 cups of sugar. The other choices are incorrect because they do not align with the proportional relationship between the amount of sugar and the number of cookies in the recipe. Choice B, 2 cups, is too few as it would be for fewer than 90 cookies. Choice C, 1.5 cups, is even less than 2 cups and doesn't fit the ratio. Choice D, 4 cups, is the amount needed for 120 cookies, not 90.

Correct Answer: B

Rationale: The military time 15:17:52 is equivalent to 3:17:52 PM in regular time. To convert from military time to regular time, we subtract 12 from the hour if it is greater than 12 to get the PM time. Therefore, 15 - 12 = 3, indicating it's in the afternoon. The correct answer is B (3:17 PM). Choice A (2:17 PM) is incorrect because 15 is greater than 12, so it would be in the afternoon. Choice C (5:17 AM) is incorrect because 15 is in the afternoon, not morning. Choice D (9:17 AM) is incorrect because 15 is in the afternoon, not morning.
