HESI A2 Math 2024 Questions
Question 1 of 5
What number is 15, if it is 20% of that number?
Correct Answer: B
Rationale: To find the number that 15 is 20% of, we set up the equation: x * 0.20 = 15. Solving for x, we get x = 15 / 0.20 = 75. Therefore, 15 is 20% of 75. Choice A, 3, is too small to be 20% of 15. Choice C, 75, is the result of the correct calculation. Choice D, 300, is too large to be 20% of 15.
Question 2 of 5
A patient's temperature is 98.6 degrees Fahrenheit. What is their temperature in degrees Celsius (1�F = 5/9�C)?
Correct Answer: A
Rationale: To convert Fahrenheit to Celsius, you need to subtract 32 from the Fahrenheit temperature (98.6�F) and then multiply the result by 5/9. Doing this calculation, you get 37�C. Choice B (32�C) is incorrect because it doesn't consider the conversion formula correctly. Choices C (41�C) and D (45�C) are incorrect as they do not apply the conversion formula accurately, leading to incorrect results.
Question 3 of 5
Express 2/5 as a decimal.
Correct Answer: C
Rationale: To express 2/5 as a decimal, you divide the numerator (2) by the denominator (5). 2 � 5 = 0.4. Choice A (0.2) is the decimal equivalent of 1/5, not 2/5. Choice B (0.25) is the decimal equivalent of 1/4, not 2/5. Choice D (2.5) is not the correct decimal equivalent of 2/5 as it is greater than 1.
Question 4 of 5
Multiply and express as a decimal: 6 55 =
Correct Answer: D
Rationale: To find the result of multiplying 6 by 55, you perform the operation 6 55, which equals 330. To express this product in decimal form, you place the decimal point one place from the right, resulting in 3.3. Therefore, the correct answer is D (3.3). Choices A, B, and C are incorrect as they do not represent the correct decimal equivalent of the multiplication of 6 and 55.
Question 5 of 5
A landscaping plan is drawn on a 1:50 scale. If a deck in the plan measures 12 cm by 10 cm, how large is the deck in real life?
Correct Answer: B
Rationale: Since the landscaping plan is drawn on a 1:50 scale, the real-life dimensions of the deck can be calculated by multiplying the dimensions on the plan by the scale factor. The dimensions given are 12 cm by 10 cm. Multiplying these dimensions by the scale factor of 50 gives us 600 cm by 500 cm, which is equivalent to 6 m by 5 m in real life. Choice A is incorrect as it doesn't consider the scale factor. Choice C and Choice D are incorrect as they are not the result of multiplying the dimensions by the scale factor.
