HESI A2 Math Practice Questions
Question 1 of 5
Subtract 2 5\8 - 7\8 and reduce.
Correct Answer: A
Rationale: To subtract 2 5\8 - 7\8, first convert both mixed numbers to improper fractions: 2 5\8 = 21\8 and 7\8 = 7\8. Then, subtract the fractions: 21\8 - 7\8 = 14\8 = 1 & 6\8. Finally, simplify the mixed number to 1 & 5\8. Choice A is correct because after subtracting, the result simplifies to 1 & 5\8. Choices B, C, and D are incorrect as they do not represent the correct result of the subtraction calculation.
Question 2 of 5
How many milliliters are in 5 liters?
Correct Answer: A
Rationale: To convert liters to milliliters, you multiply by 1000 since there are 1000 milliliters in 1 liter. So, 5 liters x 1000 = 5000 milliliters. Therefore, the correct answer is A: 5000 milliliters. B: 50 milliliters - This is incorrect as it is the result of dividing 5 liters by 100 instead of multiplying by 1000. C: 500 milliliters - This is incorrect as it is the result of multiplying 5 liters by 100 instead of 1000. D: 0.5 milliliters - This is incorrect as it is the result of dividing 5 liters by 10 instead of multiplying by 1000.
Question 3 of 5
How many kilograms are in 4,000 grams?
Correct Answer: A
Rationale: To convert grams to kilograms, we need to divide by 1000 since there are 1000 grams in a kilogram. Thus, 4,000 grams divided by 1000 equals 4 kilograms. Therefore, the correct answer is A. Choice B is incorrect as it is not the result of the correct conversion. Choice C is incorrect as it represents the equivalent of 1000 grams, not 4000 grams. Choice D is incorrect as it is half of the correct conversion result.
Question 4 of 5
Solve for x: x + 44 / 2x = 11.
Correct Answer: A
Rationale: To solve for x in the equation x + 44 / 2x = 11, we first simplify by multiplying both sides by 2x to get rid of the fraction. This gives us x^2 + 44 = 22x. Rearranging, we get x^2 - 22x + 44 = 0. This quadratic equation can be factored as (x - 11)(x - 4) = 0. Therefore, x = 11 or x = 4. However, x = 4 does not satisfy the original equation, so the correct answer is x = 11 (Choice A). Choices B, C, and D are incorrect as they do not satisfy the equation after substitution.
Question 5 of 5
What is 60% of 150?
Correct Answer: B
Rationale: To find 60% of 150, you multiply 150 by 0.6 (which represents 60%). 150 * 0.6 = 90 Therefore, the correct answer is B: 90. Choice A is incorrect as 80 is not the result of multiplying 150 by 0.6. Choice C is incorrect as 120 is not 60% of 150. Choice D is incorrect as it is the same as choice A.
