Practice Math TEAS TEST

Correct Answer: C

Rationale: To convert 45 kg to pounds, multiply by the conversion factor 2.2 lbs/kg. So, 45 kg * 2.2 lbs/kg = 99 lbs. Therefore, the correct answer is C. Choice A (120 lbs) is incorrect as it is not the result of the conversion calculation. Choice B (89 lbs) is also incorrect as it does not match the conversion result. Choice D (90 lbs) is incorrect because the correct equivalent weight is 99 lbs, not 90 lbs.

Correct Answer: B

Rationale: The correct answer is B: 1 meter. This is the best estimate for the average width of a doorway because standard doorways typically range from 0.8 to 0.9 meters wide, and rounding up to 1 meter provides a reasonable estimate. Choice A (0.5 meters) is too small for a standard doorway. Choice C (10 meters) is too large and unrealistic for a doorway. Choice D (3 meters) is wider than the typical doorway width, making it an inaccurate estimate. Therefore, B is the most appropriate estimate based on common door sizes.

Correct Answer: A

Rationale: The correct answer is A because in a proper fraction, the numerator (top number) is less than the denominator (bottom number). This indicates a fraction that is less than 1. In an improper fraction, the numerator is greater than the denominator, representing a fraction that is equal to or greater than 1. Choice B is incorrect because it reverses the definitions of proper and improper fractions. Choice C is incorrect because it suggests that a fraction is proper if the numerator is equal to the denominator, which is incorrect. Choice D is incorrect because it defines an improper fraction as having a numerator equal to the denominator, which is not the case.

Correct Answer: B

Rationale: The correct answer is B: Find all pairs of numbers that multiply to give the number. To find factors, we need to identify pairs of numbers that, when multiplied together, result in the original number. This method ensures that we consider all possible combinations of factors. Dividing the number by all possible numbers (A) is not efficient and may lead to overlooking certain factors. Listing all the multiples of the number (C) is incorrect as it focuses on multiples rather than factors. Adding the digits of the number together (D) is unrelated to finding factors.

Correct Answer: B

Rationale: To solve the equation 3(2x+5)=11x+5 for x, first distribute the 3 on the left side to get 6x+15=11x+5. Next, move all terms with x to one side by subtracting 6x from both sides to get 15=5x+5. Then, subtract 5 from both sides to get 10=5x. Finally, divide by 5 to solve for x, giving x=2. Therefore, the correct answer is B. Choice A is incorrect because x is not equal to 1. Choice C is incorrect because x is not equal to -1. Choice D is incorrect because x is not equal to -2.
