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
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 3 of 5
Convert 345 kilometers to meters (m).
Correct Answer: B
Rationale: To convert kilometers to meters, you multiply by 1000 since 1 kilometer is equal to 1000 meters. Therefore, 345 kilometers x 1000 = 345,000 meters. Choice A is incorrect as it doesn't account for the conversion factor. Choice C is incorrect as it adds an extra zero. Choice D is incorrect as it adds two extra zeros. Choice B is the correct answer as it correctly converts 345 kilometers to meters by multiplying by 1000.
Question 4 of 5
What is 0.875 converted to a fraction?
Correct Answer: A
Rationale: To convert 0.875 to a fraction, note that it is equivalent to 875/1000. Simplifying by dividing both numerator and denominator by 125 gives 7/8. This is the correct answer because it is the simplest form of the fraction. Choice B (8/7) is incorrect as it represents a fraction greater than 1. Choice C (3/4) is incorrect as it is not equivalent to 0.875. Choice D (9/10) is incorrect as it does not match the decimal value of 0.875.
Question 5 of 5
How many centimeters are in one millimeter?
Correct Answer: B
Rationale: The correct answer is B: 0.1 cm. 1 millimeter is equal to 0.1 centimeters because there are 10 millimeters in 1 centimeter. To convert millimeters to centimeters, you divide by 10. Choice A (1/100 cm) is incorrect because 1 millimeter is not equal to 1/100 of a centimeter. Choice C (1 cm) is incorrect because 1 millimeter is smaller than 1 centimeter. Choice D (10 cm) is incorrect because 1 millimeter is not equal to 10 centimeters; it is only 0.1 centimeters.
