TEAS Practice Test Math Questions
Question 1 of 5
Which of the following is the most likely weight of a pencil?
Correct Answer: D
Rationale: The correct answer is D: 25 g. A pencil is a lightweight object typically weighing in grams, not kilograms, centimeters, or milligrams. The weight of 25 g aligns with the standard weight of a pencil. Kilograms (A) are too heavy, centimeters (B) are units of length, and milligrams (C) are too light for a pencil's weight. So, the most likely weight of a pencil is 25 grams.
Question 2 of 5
A homeowner has hired two people to mow his lawn. If person A is able to mow the lawn in 2 hours by herself and person B is able to mow the lawn in 3 hours by himself, what is the amount of time it would take for both person A and B to mow the lawn together?
Correct Answer: C
Rationale: The correct answer is C: 1.2 hours. To find the combined time it takes for both A and B to mow the lawn together, we use the formula: 1/(1/A + 1/B). Substituting A=2 and B=3 into the formula, we get 1/(1/2 + 1/3) = 1/(5/6) = 6/5 = 1.2 hours. This is the time it would take for both A and B to mow the lawn together. Summary of other choices: A: 5 hours - Incorrect. This answer is obtained by simply adding the individual times of A and B, which is not the correct method for combining their work rates. B: 2.5 hours - Incorrect. This choice is halfway between the individual times of A and B, which is not the correct way to calculate the combined time. D: 1 hour - Incorrect. This choice is
Question 3 of 5
What is the approximate metric equivalent of 7 inches?
Correct Answer: D
Rationale: The correct answer is D: 17.8 cm. To convert inches to centimeters, we use the conversion factor 1 inch = 2.54 cm. So, to find the metric equivalent of 7 inches, we multiply 7 by 2.54, which equals 17.78 cm. Rounding to one decimal place gives us 17.8 cm. Explanation for incorrect choices: A: 3.2 cm - This is incorrect as it is too small for the conversion of 7 inches. B: 2.8 cm - This is also too small for the conversion of 7 inches. C: 15.4 cm - This is incorrect as it is close to the correct answer, but not the exact conversion based on the given conversion factor.
Question 4 of 5
Which of the following weights is equivalent to 3.193 kilograms?
Correct Answer: B
Rationale: To convert kilograms to grams, we multiply by 1000 since 1 kg = 1000 grams. Therefore, 3.193 kg * 1000 = 3193 grams. Choice B, 3,193 grams, is the correct equivalent weight. Choices A, C, and D are incorrect as they do not correctly convert kilograms to grams. Choice A is way too large, choice C is too small, and choice D is significantly smaller than the original weight.
Question 5 of 5
A couple dining at a restaurant receives a bill for $58.60. They wish to leave a 16% gratuity. Which of the following is the estimated gratuity?
Correct Answer: C
Rationale: To calculate the 16% gratuity on a $58.60 bill, you multiply the bill amount by 0.16 (16%). $58.60 x 0.16 = $9.38. Therefore, the estimated gratuity is $9.38 (Choice C). Incorrect Answers: A: $8.48 - Incorrect, this is not the correct calculation for a 16% gratuity on $58.60. B: $6.40 - Incorrect, this is the calculation for a 11% gratuity on $58.60. D: $7.00 - Incorrect, this is the calculation for a 12% gratuity on $58.60.
