Metric Conversions for TEAS 7 Questions

Question 1 of 5

What is 0.075 mg converted to micrograms?

Correct Answer: D

Rationale: To convert 0.075 mg to micrograms, you need to multiply by 1000 since there are 1000 micrograms in a milligram. So, 0.075 mg * 1000 = 75 mcg. Therefore, the correct answer is D: 750 mcg. Choices A, B, and C are incorrect as they do not correctly convert milligrams to micrograms.

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 does the prefix 'centi' mean?

Correct Answer: B

Rationale: The prefix 'centi' denotes the factor of 0.01. This is because 'centi' comes from the Latin word 'centum' which means one hundred. Therefore, 'centi' represents 1/100 or 0.01. The correct answer is B (0.01). Choice A (0.1) is incorrect as 'centi' is smaller than that. Choice C (0.001) is incorrect as it represents 'milli', not 'centi'. Choice D (1) is incorrect as 'centi' denotes a fraction of one, not a whole unit.

Question 4 of 5

How many kilometers (km) is equivalent to 1,000 meters?

Correct Answer: B

Rationale: To convert meters to kilometers, we divide by 1,000 since 1 kilometer is equal to 1,000 meters. Therefore, 1,000 meters divided by 1,000 equals 1 kilometer. Hence, the correct answer is B: 1 km. A: 0.1 km - Incorrect. This would be the equivalent of 100 meters. C: 10 km - Incorrect. This would be the equivalent of 10,000 meters. D: 0.01 km - Incorrect. This would be the equivalent of 10 meters.

Question 5 of 5

What is the result of multiplying 0.15 by 60?

Correct Answer: A

Rationale: To find the result of multiplying 0.15 by 60, we simply multiply the two numbers. 0.15 x 60 = 9. This is because when you multiply a decimal by a whole number, you multiply as if the decimal point isn't there and then adjust the decimal point in the final answer. Therefore, the correct answer is A: 9. Choice B (15) is incorrect as it would be the result of multiplying 0.15 by 100. Choice C (45) is incorrect as it would be the result of multiplying 0.15 by 300. Choice D (60) is incorrect as it would be the result of multiplying 1 by 60.
