HESI A2 Quizlet Math Questions

Question 1 of 5

If 3 books cost $4, how much will 6 books cost?

Correct Answer: A

Rationale: To find the cost of 6 books, we can use the proportion method. Since 3 books cost $4, 1 book costs $4/3. To find the cost of 6 books, we multiply the cost of 1 book by 6, which gives $8. Therefore, the correct answer is A: $8. The other choices are incorrect because they do not follow the logical calculation based on the initial cost of 3 books and the concept of proportionality.

Question 2 of 5

How many grams are in 4 kilograms?

Correct Answer: A

Rationale: To convert kilograms to grams, you need to multiply the number of kilograms by 1000, as there are 1000 grams in 1 kilogram. Therefore, 4 kilograms x 1000 = 4000 grams, which is the correct answer (A). Choices B, C, and D are incorrect because they do not correctly convert 4 kilograms to grams.

Question 3 of 5

The price dropped from $200 to $150. By what percentage did the price decrease?

Correct Answer: D

Rationale: To calculate the percentage decrease, we use the formula: (Original Price - New Price) / Original Price * 100%. In this case, it would be (200 - 150) / 200 * 100% = 50 / 200 * 100% = 25%. Therefore, the correct answer is D (25%). Option A (5%), B (10%), and C (20%) are incorrect as they do not accurately represent the 25% decrease in price.

Question 4 of 5

Percent (%) is a way to express a fraction with a denominator of 100. 125% can be expressed as a fraction in lowest terms. Which of the following represents 125% as a fraction?

Correct Answer: A

Rationale: 125% can be written as 125/100, which simplifies to 5/4 by dividing both numerator and denominator by the greatest common divisor (25). This is the correct fraction representation of 125%. Choice B (1/8) is incorrect as it represents 12.5%. Choice C (5/2) is incorrect as it represents 250%. Choice D (25/2) is incorrect as it represents 1250%.

Question 5 of 5

What is the solution to the equation 4y - 6 = 14? Solve for y.

Correct Answer: B

Rationale: To solve the equation 4y - 6 = 14 for y: 1. Add 6 to both sides: 4y = 20 2. Divide by 4 to isolate y: y = 5 Therefore, the correct answer is B. Choice A is incorrect as 4 is not the solution. Choices C and D are also incorrect as they do not satisfy the equation when substituted back in.
