HESI A2 Math Practice Test 2024

Correct Answer: A

Rationale: To convert fluid ounces to gallons, we know that 1 gallon is equal to 128 fluid ounces. Therefore, to find out how many gallons are in 3 fluid ounces, we divide 3 by 128 which equals 0.0234 gallons (A). Choice B (0.5 gallons) is way too high for 3 fluid ounces as it is closer to 64 fluid ounces. Choice C (0.38 gallons) and Choice D (0.12 gallons) are also incorrect as they do not align with the conversion factor of 1 gallon = 128 fluid ounces.

Correct Answer: A

Rationale: To calculate the percentage of patients satisfied, divide the number of satisfied patients (120) by the total number of patients surveyed (150) and multiply by 100. So, (120/150) x 100 = 80%. Therefore, the correct answer is A (80%). Choice B (75%) is too low, Choice C (85%) is too high, and Choice D (90%) is also too high based on the given data. Thus, the correct percentage of patients satisfied is 80%.

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: A

Rationale: To calculate the number of cakes needed, divide the total number of servings needed (70 students + 3 staff) by the number of servings per cake. Total servings needed = 70 + 3 = 73. 73 servings ÷ 24 servings per cake = 3 with a remainder of 1. Since we can't have a fraction of a cake, we need to round up to the nearest whole number. So, we need 4 cakes to ensure there are enough servings for everyone. Therefore, the correct answer is A: 4. Choice B (2) is incorrect because it doesn't provide enough servings for all students and staff members. Choice C (5) is incorrect as it would be an excessive amount of cakes. Choice D (3) is incorrect as it doesn't account for the remaining servings after dividing by 24.

Correct Answer: A

Rationale: To find the value of x, we can use the concept of proportional relationships. The ratio x:15 is equal to 120:225. To solve for x, we can set up a proportion equation: x/15 = 120/225. Cross multiply to get x = 15 * 120 / 225 = 8. Therefore, the correct answer is A: x=8. Summary: - Choice A is correct because it was derived from setting up and solving the proportion equation correctly. - Choices B, C, and D are incorrect because they do not match the solution obtained through the proportion equation.
