Metric Conversions for TEAS 7 Questions
Question 1 of 5
What is the base unit for liquid volume in the metric system?
Correct Answer: B
Rationale: The correct answer is B: Liters. Liters are the base unit for liquid volume in the metric system because they are used to measure larger volumes, making them more practical for everyday use. Milliliters are a smaller unit derived from liters, making them not the base unit. Gallons are not part of the metric system; they are commonly used in the imperial system. Choosing Liters again reinforces that it is the correct base unit for liquid volume in the metric system.
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
The prefix giga is represented by the following notation ________.
Correct Answer: A
Rationale: The correct answer is A: G. The prefix "giga" represents 10^9 in the International System of Units (SI). The symbol for "giga" is a capital letter G. It is used to denote a factor of one billion. Choice B, m, represents the prefix "milli" which is 10^-3. Choice C, Gg, is not a standard representation of the prefix "giga." Choice D, g, represents the unit of mass "gram," not the prefix "giga." Therefore, the correct notation for the prefix "giga" is A: G.
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.
