TEAS 7 Math Practice Test Questions

Question 1 of 5

Two even integers and one odd integer are multiplied together. Which of the following could be their product?

Correct Answer: D

Rationale: The product of two even integers and one odd integer will always be an even integer. This is because multiplying any number of even integers together results in an even number, and multiplying any number of odd integers together also results in an odd number. Therefore, the product could not be 3.75 (odd), 9 (odd), or 16.2 (even non-integer). The only possible option is 24, as it is an even integer and can be obtained by multiplying two even integers and one odd integer together.

Question 2 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 3 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 4 of 5

After a hurricane struck a Pacific island, donations began flooding into a disaster relief organization. The organization provided four options for donors. What percentage of the funds was donated to support construction costs?

Correct Answer: B

Rationale: The correct answer is B: 23%. To calculate this, we add up the percentages of the other three options (49% + 18% + 10% = 77%) and subtract it from 100% (100% - 77% = 23%). This gives us the percentage of funds donated to support construction costs. The rationale is that the sum of percentages of all options must add up to 100%. Choice A, C, and D are incorrect as they do not add up to 100% when combined, making B the correct answer.

Question 5 of 5

Which statement best describes the rate of change?

Correct Answer: B

Rationale: The correct answer is B because it accurately describes the rate of change as the snow melting by 5 centimeters every day. This statement represents a consistent decrease in the snow level over time. Choice A is incorrect as it implies a higher rate of melting than what is described. Choice C is incorrect as it describes an increase rather than a decrease. Choice D is also incorrect as it describes an increase instead of the intended decrease in snow level. Therefore, choice B is the most accurate representation of the rate of change in this scenario.
