Metric Conversions for TEAS 7 Questions

Question 1 of 5

What is 0.25 mg to mcg?

Correct Answer: A

Rationale: To convert mg to mcg, we need to multiply by 1000 since 1 mg = 1000 mcg. So, 0.25 mg x 1000 = 250 mcg. Therefore, the correct answer is A: 250 mcg. Choice B, C, and D are incorrect because they do not correctly convert milligrams to micrograms.

Question 2 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 3 of 5

What is 0.07 as a simplified fraction?

Correct Answer: A

Rationale: To convert 0.07 to a fraction, we need to write it as 7/100 since 0.07 is equivalent to 7/100 in fraction form. The correct answer is A (7/100). Choice B (7/50) is incorrect because 0.07 is not equivalent to 7/50. Choice C (7/25) is incorrect as well since it does not represent 0.07. Choice D (7/10) is incorrect because 0.07 is not equal to 7/10. The closest fraction to 0.07 is 7/100, making it the correct answer.

Question 4 of 5

How many milliliters are in 0.5 liters?

Correct Answer: B

Rationale: To convert liters to milliliters, you need to know that 1 liter is equal to 1000 milliliters. So, to find how many milliliters are in 0.5 liters, you multiply 0.5 by 1000, which equals 500 milliliters. Therefore, the correct answer is B: 500 mL. Choice A (50 mL) is incorrect because it is 10 times less than the correct answer. Choice C (5,000 mL) is incorrect because it is 10 times more than the correct answer. Choice D (5 mL) is incorrect because it is 100 times less than the correct answer.

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.
