TEAS 7 Math Practice Test Questions
Question 1 of 5
As part of a study, a set of patients will be divided into three groups. 4/15 of the patients will be in Group Alpha, 2/5 in Group Beta, and 1/3 in Group Gamma. Order the groups from smallest to largest, according to the number of patients in each group.
Correct Answer: B
Rationale: To determine the order of groups from smallest to largest, we need to compare the fractions given for each group. Given that 4/15 < 2/5 < 1/3: 1. Group Alpha (4/15) < Group Beta (2/5) < Group Gamma (1/3) Thus, the correct order is Group Alpha, Group Gamma, Group Beta (B). The rationale is based on comparing the fractions numerically to determine the relative sizes of the groups. The other choices are incorrect because they do not follow the order of fractions provided in the question, leading to incorrect group size comparisons.
Question 2 of 5
A lab technician took 500 milliliters of blood from a patient. The technician used 1/6 of the blood for further tests. How many milliliters of blood were used for further tests? Round your answer to the nearest hundredth.
Correct Answer: C
Rationale: To determine the amount of blood used for further tests, we first find 1/6 of 500 ml: 1/6 * 500 = 83.33 ml. Therefore, the correct answer is C (83.33 ml), rounded to the nearest hundredth. Choice A (83) is incorrect as it does not account for the decimal value. Choices B (83.3) and D (83.34) are also incorrect as they do not accurately round the calculated value to the nearest hundredth.
Question 3 of 5
Solve for x: 3(x + 4) = 18
Correct Answer: C
Rationale: To solve the equation 3(x + 4) = 18 for x, first distribute the 3: 3x + 12 = 18. Then, isolate x by subtracting 12 from both sides: 3x = 6. Finally, divide by 3 to find x = 2. Therefore, the correct answer is x = 6. Choice A is incorrect because x = 2, not 6. Choice B is incorrect because x = 4, not 6. Choice D is incorrect because x = 8, not 6.
Question 4 of 5
What is the percentage equivalent of 0.0016?
Correct Answer: D
Rationale: The correct answer is D: 0.16%. To find the percentage equivalent of a decimal, we multiply the decimal by 100. So, 0.0016 x 100 = 0.16%. Choice A (16%) is incorrect because it represents the decimal as a whole number, not a percentage. Choice B (160%) is incorrect as it incorrectly multiplies the decimal by 1000 instead of 100. Choice C (1.60%) is incorrect as it incorrectly places the decimal point in the wrong position, resulting in an incorrect percentage value.
Question 5 of 5
Simplify the following expression: 1.034 + 0.275 - 1.294
Correct Answer: A
Rationale: To simplify the expression, you first add the numbers together: 1.034 + 0.275 = 1.309. Then, subtract 1.294 from the result: 1.309 - 1.294 = 0.015. Therefore, the correct answer is A (0.015). Choices B, C, and D are incorrect as they do not match the calculated result of 0.015.
