TEAS Test Math Questions

Correct Answer: A

Rationale: To multiply fractions, you simply multiply the numerators and denominators separately. So, (3/5) * (5/8) = (3*5)/(5*8) = 15/40. However, it can be simplified to 3/8 by dividing both numerator and denominator by 5. Thus, the correct answer is A: 3/8. Choice B (3/5) is the first fraction, not the result. Choice C (15/40) is the intermediate result before simplification. Choice D (3/30) is incorrect as the numerator should be 15, not 3.

Correct Answer: A

Rationale: To convert fluid ounces to gallons, we know that 128 fluid ounces = 1 gallon. Therefore, for 1,000 fluid ounces, we divide 1,000 by 128 to get approximately 7.8125 gallons (A). The correct answer is A because it correctly represents the conversion of fluid ounces to gallons. Choices B, C, and D are incorrect because they do not accurately reflect the conversion factor. B is twice the correct answer, C is four times, and D is eight times the correct conversion.

Correct Answer: C

Rationale: To solve for x, first add 5 to both sides to isolate the variable: 3x = 21. Next, divide by 3: x = 7. Therefore, the correct answer is C (8). Choice A (7) is incorrect as the correct answer is 8. Choices B (5) and D (9) are incorrect as they are not solutions to the equation.

Correct Answer: D

Rationale: To find the area of a circle, we use the formula A = πr^2, where r is the radius. Since the diameter is 16 cm, the radius is half of that, which is 8 cm. Plugging this into the formula, A = 3.14 * 8^2 = 3.14 * 64 = 200.96 cm^2. Therefore, the correct answer is D. Choice A: 25.12 - This is incorrect as it is much smaller than the correct answer. Choice B: 50.24 - This is incorrect as it is also smaller than the correct answer. Choice C: 100.48 - This is incorrect as it is still smaller than the correct answer.

Correct Answer: C

Rationale: The correct answer is C: Zero. When two numbers are equal, their difference is always zero. This is because the distance between two equal numbers on the number line is zero. Any other choice is incorrect because a negative or positive difference implies inequality, which contradicts the premise that the numbers are equal. Choice D is also incorrect as there is sufficient information to determine the difference between two equal numbers.
