HESI A2 Math Practice Test 2024 Questions
Question 1 of 5
A seamstress is measuring a model for a new dress. The tape measure is marked in centimeters. The seamstress needs to convert that measurement into inches. If the model's waist measurement is 65.4 centimeters, what is that in inches?
Correct Answer: A
Rationale: To convert centimeters to inches, we use the conversion factor 1 inch = 2.54 centimeters. Therefore, to convert 65.4 centimeters to inches, we divide 65.4 by 2.54. The calculation is 65.4 / 2.54 = 25.74 inches. This is why choice A (25.74) is correct. Choices B, C, and D are incorrect as they do not correctly convert centimeters to inches.
Question 2 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 3 of 5
Change the following fraction into a ratio: 19/40
Correct Answer: A
Rationale: The correct answer is A: 19:40. To convert a fraction to a ratio, we simply write the numerator followed by a colon and then the denominator. In this case, 19/40 converts to 19:40. The other choices are incorrect because B switches the positions of the numbers, C simplifies the fraction incorrectly, and D simplifies the fraction to a different ratio. Therefore, the correct answer is A as it accurately represents the ratio of 19 to 40.
Question 4 of 5
Ratio and proportion: 6:10=24:x
Correct Answer: A
Rationale: To find x in the proportion 6:10=24:x, we first calculate the ratio of the given numbers, 6/10=24/x. Simplifying, we get 0.6=24/x. Cross multiplying, we get x=24/0.6=40. Therefore, the correct answer is A. Choice B is incorrect as it does not satisfy the proportion. Choice C is incorrect as it is too large compared to the correct answer. Choice D is incorrect as it is too small compared to the correct answer.
Question 5 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.
