HESI A2 Math Practice Test 2024 Questions

Question 1 of 5

Change the following decimal to a percent: 0.09

Correct Answer: A

Rationale: To convert a decimal to a percent, you multiply by 100. In this case, 0.09 * 100 = 9%. Therefore, the correct answer is A: 9%. Choice B (90%) is incorrect as it would be the result of multiplying by 1000, not 100. Choice C (1%) is incorrect as it would be the result of moving the decimal point two places to the right without multiplying by 100. Choice D (0%) is incorrect as the number is not zero, it's 0.09.

Question 2 of 5

If a student earns $120 for a 10-hour tutoring session and works 6 hours, how much did the student earn?

Correct Answer: A

Rationale: To find how much the student earned for working 6 hours, we can use the formula: Earnings = (Total pay / Total hours) x Hours worked. In this case, Earnings = ($120 / 10 hours) x 6 hours = $72. Therefore, the correct answer is A: $72. Choice B, $90, is incorrect as it does not match the calculated amount. Choice C, $80, is also incorrect. Choice D, $50, is incorrect because it is too low based on the calculated earnings for 6 hours.

Question 3 of 5

Multiply 4/9 x 1 & 4/5 x 2/5.

Correct Answer: C

Rationale: To multiply 4/9 by 1 & 4/5 by 2/5, we first multiply the fractions separately. 4/9 x 1 = 4/9, 4/5 x 2/5 = 8/25. Then we multiply the results: 4/9 x 8/25 = (4 x 8) / (9 x 25) = 32 / 225 = 8/25. Therefore, the correct answer is C. Choices A, B, and D are incorrect because they do not result from the correct multiplication of the given fractions.

Question 4 of 5

25 1/7 - 12 5/7 = ?

Correct Answer: A

Rationale: To subtract mixed numbers, start by subtracting the whole numbers (25 - 12 = 13). Then subtract the fractions separately (1/7 - 5/7 = -4/7). Combine the whole number and fraction results to get 13 - 4/7 = 12 3/7, which is choice A. Other choices are incorrect as they do not match the correct result after the subtraction process. Choice B doesn't account for the fraction subtraction correctly. Choice C is not the correct result of the subtraction. Choice D is the result of only subtracting the whole numbers, ignoring the fractions.

Question 5 of 5

An architect is designing a rectangular room. The room has an area of 225 square feet and a width of 15 feet. What is the length of the room?

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.
