Metric Conversions for TEAS 7 Questions
Question 1 of 5
How many millimeters are in 0.75 centimeters?
Correct Answer: C
Rationale: To convert from centimeters to millimeters, you multiply by 10 since there are 10 millimeters in 1 cm. Therefore, to find how many millimeters are in 0.75 cm, you multiply 0.75 by 10, which equals 7.5 mm. Therefore, the correct answer is C: 75 mm. Choice A: 7.5 mm is the result of the correct conversion. Choice B: 0.75 mm is incorrect as it's the original value, not the converted value. Choice D: 75 cm is incorrect as the question asks for millimeters, not centimeters.
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
Convert 250 milliliters to liters.
Correct Answer: B
Rationale: To convert milliliters to liters, we must divide by 1000 since there are 1000 milliliters in 1 liter. Therefore, 250 milliliters divided by 1000 equals 0.25 liters (choice B). Choice A is incorrect as it is 10 times the correct answer. Choice C is incorrect as it is 5 times the correct answer. Choice D is incorrect as it is 1/10th of the correct answer. Thus, the correct conversion is 0.25 liters.
Question 4 of 5
Convert 34.5 grams to kilograms (kg).
Correct Answer: A
Rationale: To convert grams to kilograms, you need to divide by 1000 since there are 1000 grams in 1 kilogram. Therefore, 34.5 grams divided by 1000 equals 0.0345 kilograms or 3.45 kg (A). The other choices are incorrect because B is the original value in kg, C is 100 times the value in kg, and D is the original value in grams.
Question 5 of 5
What is 0.5 liters in ml?
Correct Answer: A
Rationale: To convert liters to milliliters, you multiply by 1000 since 1 liter = 1000 ml. Therefore, 0.5 liters x 1000 = 500 ml. Thus, the correct answer is A (500 ml). Choice B (50 ml) is incorrect as it is 10 times smaller than the correct answer. Choice C (5 ml) is incorrect as it is 100 times smaller than the correct answer. Choice D (0.5 ml) is incorrect as it is the same value in milliliters, not the conversion of liters to milliliters.
