TEAS Practice Math Test Questions
Question 1 of 5
Which of the following is listed in order from least to greatest?
Correct Answer: C
Rationale: To determine the order from least to greatest, convert all fractions to decimal equivalents. -2 3/4 = -2.75 -2 7/8 = -2.875 -1/5 = -0.2 1/8 = 0.125 2/5 = 0.4 Now arrange them in ascending order: -2.875, -2.75, -0.2, 0.125, 0.4 Therefore, the correct order from least to greatest is -2 7/8, -2 3/4, -1/5, 1/8, 2/5 (Option C). Other choices are incorrect as they do not follow the correct order of the numbers when arranged from least to greatest.
Question 2 of 5
Dr. Lee observed that 30% of all his patients developed an infection after taking a certain antibiotic. He further noticed that 5% of that 30% required hospitalization to recover from the infection. What percentage of Dr. Lee's patients were hospitalized after taking the antibiotic?
Correct Answer: A
Rationale: To calculate the percentage of Dr. Lee's patients hospitalized, we need to find 5% of the 30% who developed an infection. 5% of 30% is 1.5%. Therefore, the correct answer is A: 1.50%. Choice B (5%) is incorrect because it represents the percentage of patients who developed an infection, not those hospitalized. Choice C (15%) is incorrect as it is the total percentage of patients who developed an infection, not just those hospitalized. Choice D (30%) is incorrect as it represents the initial percentage of patients who developed an infection, not those hospitalized.
Question 3 of 5
A patient requires a 30% decrease in their medication dosage. Their current dosage is 340 mg. What will their dosage be after the decrease?
Correct Answer: B
Rationale: To calculate the new dosage after a 30% decrease, we multiply the current dosage (340 mg) by (100% - 30%) = 70%. 340 mg * 70% = 340 mg * 0.70 = 238 mg. Therefore, the correct answer is B. Choice A (70 mg): This is incorrect because it represents a 30% decrease from 100 mg, not the initial dosage of 340 mg. Choice C (270 mg): This is incorrect because it does not account for the 30% decrease from the initial dosage of 340 mg. Choice D (340 mg): This is incorrect because the question asks for the dosage after a 30% decrease, not the current dosage.
Question 4 of 5
What is the mode of the numbers in the distribution shown in the table?
Correct Answer: A
Rationale: The mode is the value that appears most frequently in a set of numbers. In this distribution, the number 1 appears the most times (5 times), making it the mode. Choice A is correct. Choices B, C, and D are incorrect because they do not represent the value that appears most frequently in the distribution.
Question 5 of 5
Which of the following is listed in order from least to greatest?
Correct Answer: C
Rationale: To determine the order from least to greatest, convert all fractions to decimal equivalents. -2 3/4 = -2.75 -2 7/8 = -2.875 -1/5 = -0.2 1/8 = 0.125 2/5 = 0.4 Now arrange them in ascending order: -2.875, -2.75, -0.2, 0.125, 0.4 Therefore, the correct order from least to greatest is -2 7/8, -2 3/4, -1/5, 1/8, 2/5 (Option C). Other choices are incorrect as they do not follow the correct order of the numbers when arranged from least to greatest.
