TEAS Practice Test Math

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.

Correct Answer: A

Rationale: The correct answer is A because to convert pounds to kg, you need to multiply by the conversion factor of 2.2, and to convert kg to pounds, you need to divide by 2.2. This is because 1 pound is equal to 0.453592 kg, which is approximately 2.2 pounds per kg. Therefore, multiplying by 2.2 for pounds and dividing by 2.2 for kg ensures the correct conversion between the two units. Choices B, C, and D are incorrect because they do not correspond to the correct conversion factor between pounds and kg.

Correct Answer: A

Rationale: The correct answer is A: One. When the number 1 is raised to any power, the result is always 1. This is because any number raised to the power of 1 is equal to that number itself. In this case, 1 raised to any power will always be 1. Summary: Choice B (Itself) is incorrect because raising 1 to any power does not result in the number itself, but always in 1. Choice C (Zero) is incorrect as any number raised to the power of 0 is 1, not 0. Choice D (Two) is incorrect as it is not possible for 1 raised to any power to equal 2.

Correct Answer: C

Rationale: To convert a percentage to a decimal, you divide by 100. In this case, 87.5% divided by 100 is 0.875. Therefore, choice C, 0.875, is the correct decimal form of 87.5%. Choices A and B are incorrect as they do not represent the correct decimal value. Choice D, 8.75, is also incorrect as it is the decimal form of 875%.

Correct Answer: B

Rationale: To find the number of students in the respiratory care program, we need to calculate the percentage of students in that program based on the pie chart. The respiratory care program occupies 19% of the pie chart. 19% of 800 students is 0.19 * 800 = 152. Therefore, the correct answer is B: 152. Choice A (336) is incorrect as it represents the percentage of students in a different program, not respiratory care. Choice C (144) and Choice D (168) are also incorrect as they do not correspond to the percentage allocated for the respiratory care program in the pie chart.
