HESI A2 Quizlet Math Questions
Question 1 of 5
In a survey, 120 people were asked if they could swim. If 85% said they could, how many people could swim?
Correct Answer: B
Rationale: To find the number of people who can swim, multiply the total number of people surveyed by the percentage that can swim. In this case, 120 x 0.85 = 102. Choice B is correct. Choice A is too low as it doesn't account for the 85%. Choice C is too high. Choice D is also too low.
Question 2 of 5
How many gallons are in 16 quarts?
Correct Answer: C
Rationale: To convert quarts to gallons, we know that 1 gallon equals 4 quarts. Therefore, to find out how many gallons are in 16 quarts, we divide 16 by 4 which equals 4 gallons. So, the correct answer is C. Explanation of other choices: A: 1 gallon is not the correct answer because 16 quarts is more than 1 gallon. B: 8 gallons is incorrect as it does not align with the conversion factor of 1 gallon per 4 quarts. D: 4.5 gallons is incorrect as it is not the result of dividing 16 quarts by the conversion factor of 4 quarts per gallon.
Question 3 of 5
In a class of 28 people, there are 12 men and 16 women. What is the ratio of men to women?
Correct Answer: A
Rationale: To find the ratio of men to women, divide the number of men by the number of women. So, 12 men / 16 women = 3/4. Therefore, the correct ratio is 3:4 (Choice A). Choice B is incorrect as it does not simplify to 3:4. Choice C is incorrect as it uses the total number of people instead of men and women. Choice D is incorrect because it simplifies to 1:2, not 3:4.
Question 4 of 5
Calculate the product of the following decimals: (0.67)(0.09)
Correct Answer: A
Rationale: To calculate the product of decimals, you multiply the numbers as if they were whole numbers, then adjust the decimal places. Step 1: Multiply 67 by 9 (67 * 9 = 603) Step 2: Count the total decimal places in the original numbers (2) Step 3: Place the decimal point in the product by counting from the right the same number of places as in step 2, which gives 0.0603. Therefore, the correct answer is A: 0.0603. Other choices are incorrect because they do not follow the correct multiplication and decimal placement process. B: 0.6, C: 0.603, and D: 0.06 have incorrect decimal placement or incorrect multiplication results.
Question 5 of 5
What percentage of her income is left after Mary spent 15%?
Correct Answer: B
Rationale: To find the percentage of income left after spending 15%, you subtract 15% from 100% (total income percentage). So, 100% - 15% = 85% left. Therefore, choice B (85%) is correct. Choices A, C, and D are incorrect as they do not accurately represent the remaining percentage of income after spending.
