HESI A2 Math Practice Exam Questions
Question 1 of 5
Convert 5 3/4 to a decimal. Round to the nearest tenth.
Correct Answer: C
Rationale: To convert 5 3/4 to a decimal, first convert the mixed number to an improper fraction: 5 3/4 = (4*5 + 3)/4 = 23/4. Then, divide the numerator by the denominator to get the decimal: 23 ÷ 4 = 5.75. Rounding to the nearest tenth gives 5.8, which is choice C. Choices A, B, and D are incorrect because they do not accurately represent the decimal equivalent of 5 3/4 rounded to the nearest tenth.
Question 2 of 5
Sally was able to eat 5/8 of her lunch. John ate 75% of his lunch. Who ate more?
Correct Answer: A
Rationale: Certainly! To compare, we need to convert both fractions to a common denominator. LCM of 8 and 100 (8*25) is 100. Sally ate (5/8)*100 = 62.5%. John ate 75%. Clearly, 75% is more than 62.5%. So, John ate more. Other choices are incorrect as they do not consider the actual percentages consumed by Sally and John.
Question 3 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 4 of 5
If 9 out of 75 band members missed practice, what percentage of band members missed practice?
Correct Answer: B
Rationale: To find the percentage of band members who missed practice, we need to calculate the ratio of band members who missed practice to the total band members. 9 out of 75 band members missed practice, so the ratio is 9/75 = 0.12 or 12%. Therefore, the correct answer is B (12%). Choice A (10%) is incorrect as 9 out of 75 is not equivalent to 10%. Choice C (15%) is incorrect as 9 out of 75 is not equivalent to 15%. Choice D (18%) is incorrect as 9 out of 75 is not equivalent to 18%.
Question 5 of 5
A clinic sees an average of 25 patients every 4 hours. If the clinic is open for 8 hours, how many patients will they see in total?
Correct Answer: D
Rationale: To find the total number of patients seen in 8 hours, first calculate the number of patients seen in 1 hour (25/4 = 6.25). Then, multiply by 8 to get the total (6.25 * 8 = 50). Therefore, the correct answer is D. Choices A, B, and C are incorrect because they do not follow the correct calculation process. A, B, and C do not consider the rate of patients seen per hour or the total hours the clinic is open.
