Math HESI A2 Practice Test Questions
Question 1 of 5
Add: 3 1/8 + 1 1/4.
Correct Answer: A
Rationale: To add 3 1/8 and 1 1/4, first convert both to improper fractions: 3 1/8 = 25/8 and 1 1/4 = 5/4. Then, add the fractions: 25/8 + 5/4 = 50/8 + 10/8 = 60/8 = 7 1/2. Convert 7 1/2 back to a mixed number: 7 1/2 = 6 2/8 = 6 1/4 = 4 3/8, which is the correct answer (A). Choice B (4 1/2) is incorrect as it doesn't match the calculated sum. Choice C (4 3/4) is incorrect as it is not the simplified form of the sum. Choice D (5 1/4) is incorrect as it is higher than the calculated sum.
Question 2 of 5
A marathon runner is training for her next race. On her weekly weekend run she completes 21.4 miles and burns 2276 calories. What is her rate of calories burned per mile?
Correct Answer: A
Rationale: To find the rate of calories burned per mile, divide the total calories burned (2276) by the total miles ran (21.4). So, 2276 / 21.4 = 106.4. This means the runner burns approximately 106.4 calories per mile. Choice A (106.4) is correct as it represents the correct calculation result. Choices B, C, and D are incorrect as they do not match the calculated value based on the given information.
Question 3 of 5
If a runner runs 5 miles in 45 minutes, what is their average speed in miles per hour?
Correct Answer: A
Rationale: To calculate average speed, divide total distance by total time. In this case, 5 miles in 45 minutes equals 5/0.75 = 6.67 mph. Choice A is correct because it correctly calculates the average speed based on the given information. Choices B, C, and D are incorrect as they do not accurately calculate the average speed.
Question 4 of 5
Convert 1/5 to a decimal.
Correct Answer: B
Rationale: To convert 1/5 to a decimal, you divide 1 by 5. This gives you 0.2, which is the correct answer (B). Choice A (0.5) is the decimal equivalent of 1/2, not 1/5. Choice C (1.5) is the sum of 1 and 1/2. Choice D (0.15) is the decimal equivalent of 15/100, not 1/5. Therefore, the correct answer is B (0.2).
Question 5 of 5
You need to buy cardboard to cover a rectangular box with dimensions 40cm by 30cm by 25cm. Considering only the exterior surfaces (not flaps or openings), how much cardboard do you need (assume one sheet covers 0.5 sq m)?
Correct Answer: C
Rationale: To calculate the surface area of the rectangular box, you need to find the area of each face. The box has 6 faces, and each face's area is 40*30cm=1200cm². Therefore, the total surface area is 6*1200cm²=7200cm²=0.72m². Since one sheet covers 0.5m², you need 0.72m²/0.5m²=1.2 sheets of cardboard, which is equivalent to 1.2m². This is why option C, 1.2 sq m, is the correct answer. Option A (0.3 sq m), B (0.6 sq m), and D (1.8 sq m) are incorrect as they do not align with the correct calculation of the surface area of the rectangular box.
