Practice Math TEAS TEST

Correct Answer: A

Rationale: The correct answer is A because a factor is a number that can be multiplied by another number to give the original number. For example, in the case of 6, factors would be 1, 2, 3, and 6. These numbers can be multiplied to get 6. Choice B is incorrect because it describes a divisor. Choice C is incorrect as it does not specifically define a factor but rather a relationship between two numbers. Choice D is incorrect as factors can be numbers less than, equal to, or greater than 1.

Correct Answer: C

Rationale: The correct answer is C (12.325 mL). To calculate this, first, convert 2.5 teaspoons to mL by multiplying by 4.93: 2.5 * 4.93 = 12.325 mL. Choice A (5.33 mL) is incorrect because it is less than the correct amount. Choice B (7.43 mL) is also incorrect as it is lower than the correct value. Choice D (0.507 mL) is incorrect because it is significantly lower than the correct amount. Therefore, the correct answer is C as it accurately reflects the conversion of teaspoons to milliliters based on the given conversion rate.

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: D

Rationale: To find the portion each of the other three friends received, we first calculate what fraction of the pizza was left after one friend ate half. Half of the pizza is 1/2, so 1 - 1/2 = 1/2 is left. Then, we divide 1/2 equally among the three friends, giving each 1/2 ÷ 3 = 1/6. Therefore, each of the other three friends received 1/6 of the pizza. Summary: A: 1/5 - Incorrect. Not the correct division after one friend ate half. B: 1/3 - Incorrect. The correct division is not one-third after one friend ate half. C: 1/4 - Incorrect. The correct division is not one-fourth after one friend ate half.

Correct Answer: A

Rationale: The correct answer is A: One. Any number raised to the power of zero equals one. This is because the rule for exponents states that any number raised to the power of zero is equal to one, regardless of the base number. This rule is derived from the properties of exponents and is a fundamental concept in mathematics. Choices B, C, and D are incorrect because raising a number to the power of zero does not result in the number itself, zero, or two. The key to remember is that any number raised to the power of zero is always equal to one, making choice A the correct answer.
