HESI A2 Math Practice Test

1. At the fair, Serena sold 6 fewer balloons than Tommy, who sold 2 more balloons than Uri. If Uri sold 28 balloons, how many did Serena sell?

A. 20
B. 22
C. 24
D. 32

Correct answer: C

Rationale: If Uri sold 28 balloons, Tommy sold 28 + 2 = 30 balloons. Since Serena sold 6 fewer balloons than Tommy, she sold 30 - 6 = 24 balloons. Therefore, Serena sold 24 balloons. Choice A, 20 balloons, is incorrect because it doesn't consider the difference in sales between Serena and Tommy. Choice B, 22 balloons, is incorrect as it doesn't account for the correct relation between Tommy and Serena's sales. Choice D, 32 balloons, is incorrect as it doesn't align with the given information about the sales differences.

2. How many ounces are in a ton?

A. 32,000 ounces
B. 30,000 ounces
C. 35,000 ounces
D. 40,000 ounces

Correct answer: A

Rationale: The correct answer is A: 32,000 ounces. A ton is equivalent to 2,000 pounds. Since each pound contains 16 ounces, you can calculate the total number of ounces in a ton by multiplying 2,000 pounds by 16 ounces, which equals 32,000 ounces. Choice B (30,000 ounces), Choice C (35,000 ounces), and Choice D (40,000 ounces) are incorrect because they do not correctly calculate the number of ounces in a ton based on the conversion of pounds to ounces.

3. 15\25 + 42\52 = ?

A. 1 3/10
B. 1 1/10
C. 1\10\2024
D. 3\10\2024

Correct answer: A

Rationale: 15\25 + 42\52 simplifies to 1 3\10.

4. Subtract 2 5\8 - 7\8 and reduce.

A. 1 & 5\8
B. 1 & 1\4
C. 1 & 6\8
D. 1 & 3\4

Correct answer: A

Rationale: Subtract the fractions first: 2 5\8 - 7\8 = 1 & 5\8.

5. How many ounces are in 3 pints?

A. 24 ounces
B. 48 ounces
C. 32 ounces
D. 64 ounces

Correct answer: B

Rationale: To find out how many ounces are in 3 pints, you need to multiply the number of pints by the number of ounces in 1 pint. Since there are 16 ounces in 1 pint, 3 pints equal 3 * 16 = 48 ounces. Therefore, the correct answer is 48 ounces. Choice A (24 ounces) is incorrect because it miscalculates the conversion. Choice C (32 ounces) is incorrect as it does not correctly apply the conversion factor. Choice D (64 ounces) is incorrect as it doubles the correct answer, showing a misunderstanding of the conversion.
