Metric Conversions for TEAS 7 Questions
Question 1 of 5
What is 0.1 mg to mcg?
Correct Answer: A
Rationale: To convert milligrams (mg) to micrograms (mcg), you multiply by 1000. So, 0.1 mg x 1000 = 100 mcg, which is the correct answer (A). The other choices are incorrect because: B: 10 mcg - Incorrect, as it is the result of multiplying by 100, not 1000. C: 1000 mcg - Incorrect, as this is the equivalent of 1 mg, not 0.1 mg. D: 1 mcg - Incorrect, as it is the result of dividing by 1000, not multiplying.
Question 2 of 5
What is 0.875 as a fraction?
Correct Answer: A
Rationale: To convert 0.875 to a fraction, we can write it as 875/1000 and simplify it to 7/8 by dividing both the numerator and denominator by 125. The correct answer is A (7/8). Choice B (9/10) is incorrect as it does not represent 0.875. Choices C (5/6) and D (3/4) are also incorrect fractions as they do not equal 0.875 when converted.
Question 3 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 4 of 5
Convert 0.75 kilograms to grams.
Correct Answer: B
Rationale: To convert kilograms to grams, you need to multiply by 1000 since 1 kilogram is equal to 1000 grams. So, 0.75 kg * 1000 = 750 grams. Therefore, choice B (750 grams) is correct. Choice A (75 grams) is incorrect as it is a decimal point off; choice C (7,500 grams) is incorrect as it is off by a factor of 10; and choice D (75,000 grams) is incorrect as it is off by a factor of 100.
Question 5 of 5
Convert 0.20 liters to milliliters. What is the equivalent volume?
Correct Answer: A
Rationale: To convert 0.20 liters to milliliters, we know that 1 liter is equal to 1000 milliliters. Therefore, 0.20 liters = 0.20 x 1000 = 200 milliliters. So, the correct answer is A: 200 ml. Choice B (20 ml) is incorrect as it represents 0.02 liters. Choice C (2 ml) is incorrect as it represents 0.002 liters. Choice D (2000 ml) is incorrect as it is the result of incorrectly multiplying 0.20 liters by 1000 twice.
