HESI A2 Math Practice Test 2024

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: D

Rationale: To find 25% of 400, you multiply 400 by 0.25 (25% as a decimal). So, 400 * 0.25 = 100. Therefore, the correct answer is D. Choice A (800) is incorrect as it is 200% of 400. Choice B (10,000) is incorrect as it is 2500% of 400. Choice C (200) is incorrect as it is 50% of 400.

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: B

Rationale: To find the length of the room, we use the formula for the area of a rectangle: Area = Length x Width. Given that the area is 225 sq ft and the width is 15 ft, we can substitute these values into the formula: 225 = Length x 15. Solving for Length, we get Length = 225 / 15 = 15 feet. Therefore, the correct answer is B: 15 feet. Choice A (30 feet) is incorrect because it is twice the width and does not align with the given area. Choice C (25 feet) is incorrect because it does not satisfy the area requirement. Choice D (45 feet) is incorrect as it is not consistent with the given width and area.

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.
