Metric Conversions for TEAS 7

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.

Correct Answer: D

Correct Answer: A

Rationale: To convert liters to milliliters, you multiply by 1000 because 1 liter is equal to 1000 milliliters. So, 0.5 liters x 1000 = 500 milliliters. Therefore, the correct answer is A: 500 milliliters. Choices B, C, and D are incorrect because they do not follow the correct conversion factor from liters to milliliters. B is too small, C is even smaller, and D is a decimal value that does not represent a proper conversion.

Correct Answer: A

Rationale: To convert nanometers to meters, we need to remember that nano- is a prefix meaning 10^-9. Therefore, 1 nanometer is equal to 10^-9 meters. So, the correct answer is A: 10^-9 meters. Explanation for why other choices are incorrect: - B: 10^-6 meters is the equivalent of a micrometer, not a nanometer. - C: 10^-12 meters is the equivalent of a picometer, which is smaller than a nanometer. - D: 10^-15 meters is the equivalent of a femtometer, which is much smaller than a nanometer.

Correct Answer: B

Rationale: To convert 0.1 liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in 1 liter. So, 0.1 * 1000 = 100 ml, which is the correct answer (B). Choice A (10 ml) is incorrect as it represents 0.01 liters, choice C (1000 ml) is incorrect as it represents 1 liter, and choice D (1 ml) is incorrect as it is too small for 0.1 liters.
