HESI A2 Math Practice Exam Questions
Question 1 of 5
What is the result of 32 divided by 8/9?
Correct Answer: C
Rationale: To solve 32 divided by 8/9, we convert the division to multiplication by taking the reciprocal of 8/9, which is 9/8. So, 32 ÷ 8/9 becomes 32 x 9/8. Multiply numerators (32 x 9 = 288) and denominators (8) to get 288/8 = 36. Therefore, the correct answer is C: 36. Explanation for other choices: A: 4 & 1/9 - Incorrect because the result is a whole number, not a mixed number. B: 4 - Incorrect as it does not account for the fraction involved in the division. D: 28 & 4/9 - Incorrect as it is not the result of the division calculation.
Question 2 of 5
How many ounces are in 3 pints?
Correct Answer: B
Rationale: To convert pints to ounces, we know that 1 pint is equal to 16 ounces. Therefore, 3 pints would be 3 x 16 = 48 ounces. This makes choice B the correct answer. Choice A (24 ounces) is incorrect as it represents only 1 pint, not 3. Choice C (32 ounces) and choice D (64 ounces) are also incorrect as they do not accurately reflect the conversion of pints to ounces.
Question 3 of 5
Evaluate the following expression: -x + y + xy, when x = 4 and y = 2.
Correct Answer: B
Rationale: To evaluate the expression -x + y + xy with x = 4 and y = 2: Substitute x and y values: -4 + 2 + 4(2) = -4 + 2 + 8 = 6 (B). Explanation: Follow the order of operations (PEMDAS) to simplify the expression correctly. Option A is incorrect as it does not match the result obtained. Option C is incorrect as it does not consider the negative sign in the expression. Option D is incorrect as it does not account for the addition and multiplication operations in the expression.
Question 4 of 5
Convert 0.007 kilograms to grams.
Correct Answer: A
Rationale: To convert 0.007 kilograms to grams, you should multiply by 1000 since there are 1000 grams in a kilogram. So, 0.007 kg * 1000 = 7 grams (Option A). Option B is incorrect as it incorrectly multiplies by 10 instead of 1000. Option C and D mistakenly move the decimal point to the wrong place.
Question 5 of 5
How many centimeters are in a foot?
Correct Answer: C
Rationale: The correct answer is C: 30.48 cm. The conversion factor for feet to centimeters is 1 foot = 30.48 cm. To convert feet to centimeters, you multiply the number of feet by 30.48. Therefore, there are 30.48 cm in a foot. Choice A (30 cm) and Choice B (31.5 cm) are incorrect because they do not accurately represent the conversion factor from feet to centimeters. Choice D (35 cm) is also incorrect because it is not the standard conversion factor for feet to centimeters. Be sure to use the correct conversion factor of 30.48 cm when converting between feet and centimeters.
