HESI A2 Math 2024 Questions

Question 1 of 5

Temperature Conversion & Interpretation: A patient's body temperature is 102�F. Convert this to �C and assess if it indicates a fever.

Correct Answer: C

Rationale: Rationale: 1. To convert Fahrenheit to Celsius, you can use the formula: �C = (�F - 32) x 5/9. 2. Given that the patient's body temperature is 102�F, we can calculate the equivalent temperature in Celsius: �C = (102 - 32) x 5/9 �C = 70 x 5/9 �C = 350/9 �C ≈ 38.9�C, which can be rounded to 39�C. 3. A body temperature of 39�C is considered to indicate a fever. Normal body temperature typically ranges from 36.1�C to 37.2�C, so a temperature of 39�C is higher than the normal range and suggests a fever. 4. Options A and B are incorrect as they do not reflect the conversion of 102�F to �C

Question 2 of 5

Divide: 5 � 9 =

Correct Answer: B

Rationale: When dividing 5 by 9, you are finding how many times 9 can fit into 5. Since 9 is greater than 5, the result will be less than 1. Therefore, 5 � 9 equals 0.555... which is approximately 0.5. Choice A (0.05) is incorrect because it implies a smaller value than the correct answer. Choice C (5) is incorrect as it is not the result of dividing 5 by 9. Choice D (50) is incorrect as it is a much larger value than the correct answer.

Question 3 of 5

If a package of 10 pencils is divided between every 2 students in a class with 20 students, how many pencils are needed?

Correct Answer: D

Rationale: If 20 students are divided into pairs, there would be 10 pairs in total (20 students / 2 = 10 pairs). Since each pair receives 10 pencils, the total number of pencils needed is calculated by multiplying the number of pairs (10 pairs) by the number of pencils each pair receives (10 pencils per pair), resulting in 100 pencils required. Therefore, the correct answer is 100 pencils. Choices A, B, and C are incorrect because they do not consider the correct pairing of students or the total number of pencils needed for each pair.

Question 4 of 5

What is 60% of 90?

Correct Answer: A

Rationale: To find 60% of 90, you multiply 90 by 0.60 (which is the decimal form of 60%). So, 90 * 0.60 = 54. Therefore, 60% of 90 is 54. Choice A is correct. Choice B, C, and D are incorrect as they do not reflect the correct calculation for finding 60% of 90.

Question 5 of 5

Express the ratio of 25:80 as a percentage.

Correct Answer: A

Rationale: To express the ratio 25:80 as a percentage, follow these steps: First, divide 25 by 80: 25/80 = 0.3125. Then, multiply by 100 to convert to a percentage: 0.3125 100 = 31.25%. Therefore, the ratio 25:80 is equivalent to 31.25%. Choice A is correct. Choice B (34%) is incorrect because it does not accurately represent the ratio 25:80. Choice C (41.25%) and Choice D (43.75%) are also incorrect as they do not match the calculated percentage for the given ratio.
