Metric Conversions for TEAS 7 Questions
Question 1 of 5
What is 0.025 mg in mcg?
Correct Answer: A
Rationale: To convert mg to mcg, you need to multiply by 1000. Therefore, 0.025 mg x 1000 = 25 mcg. The correct answer is A (25 mcg). Choice B (250 mcg) is incorrect as it incorrectly multiplies by 10 instead of 1000. Choice C (2.5 mcg) is incorrect as it drops a zero from the conversion. Choice D (0.25 mcg) is incorrect as it adds an extra zero to the answer.
Question 2 of 5
What mnemonic helps in recalling metric conversions?
Correct Answer: A
Rationale: The correct answer is A: King Hector Died By Drinking Chocolate Milk. This mnemonic stands for kilo, hecto, deka, base unit, deci, centi, milli - the order of metric prefixes. It helps remember the order and conversion factors for metric units. Choice B is irrelevant and does not relate to metric conversions. Choice C is too general and does not provide a specific mnemonic for metric conversions. Choice D does not provide any helpful information or mnemonic for recalling metric conversions.
Question 3 of 5
What is 0.5 multiplied by 20?
Correct Answer: A
Rationale: To calculate 0.5 multiplied by 20, you simply multiply 0.5 by 20, which equals 10. The correct answer is A (10). The other choices are incorrect because: B (15) is the result of 0.5 multiplied by 30. C (20) is the original number being multiplied, not the result. D (25) is the result of 0.5 multiplied by 50, not 20.
Question 4 of 5
Convert 5,000 milligrams to grams.
Correct Answer: B
Rationale: To convert milligrams to grams, we divide by 1000 since there are 1000 milligrams in a gram. Therefore, 5,000 mg ÷ 1000 = 5 grams. Choice B is correct. Choice A (50 grams) is incorrect as it is 10 times the correct answer. Choice C (500 grams) is incorrect as it is 100 times the correct answer. Choice D (0.05 grams) is incorrect as it is 100 times less than the correct answer.
Question 5 of 5
Convert 0.04 grams to milligrams.
Correct Answer: A
Rationale: To convert grams to milligrams, you need to multiply by 1000 since there are 1000 milligrams in 1 gram. So, 0.04 grams x 1000 = 40 mg. Therefore, the correct answer is A. Choice B is incorrect because it's 10 times smaller than the correct answer. Choice C is incorrect because it's 100 times larger than the correct answer. Choice D is incorrect because it's 100 times smaller than the correct answer.
