Metric Conversions for TEAS 7

1. What mnemonic helps in recalling metric conversions?

Correct answer: A

Rationale: The mnemonic 'King Hector Died By Drinking Chocolate Milk' aids in recalling metric prefixes in order: kilo-, hecto-, deca-, base (meter, liter, gram), deci-, centi-, milli-. Choice B does not provide a relevant mnemonic for metric conversions. Choices C and D do not offer a helpful phrase for remembering metric prefixes, making them incorrect.

2. In the metric system, what factor does the prefix kilo- represent?

Correct answer: A

Rationale: The prefix 'kilo-' in the metric system signifies a factor of 1000, which is equivalent to 10^3. Therefore, when using the prefix 'kilo-', it implies multiplying the base unit by 1000. For instance, one kilometer is equal to 1000 meters. Choices B, C, and D are incorrect as they do not accurately represent the factor associated with the prefix 'kilo-'.

3. What is 0.5 liters in milliliters?

Correct answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 because 1 liter is equal to 1000 milliliters. Therefore, when you convert 0.5 liters to milliliters, you get 500 milliliters (0.5 * 1000 = 500). This conversion is commonly used in various situations where different units of volume are required. Choices B, C, and D are incorrect because they do not follow the correct conversion factor between liters and milliliters.

4. Convert 0.875 to a fraction,

Correct answer: A

Rationale: To convert 0.875 to a fraction, express it as 875\10000. Simplifying this fraction by dividing both the numerator and denominator by 125 results in 7\80.

5. What is 0.05 mg in mcg?

Correct answer: A

Rationale: 0.05 mg is equivalent to 50 mcg because 1 mg is equal to 1000 mcg. To convert milligrams to micrograms, you need to multiply by 1000. Therefore, 0.05 mg x 1000 = 50 mcg. Choices B, C, and D are incorrect because they do not correctly convert milligrams to micrograms. Option B (500 mcg) would be the result if the conversion was done incorrectly by adding an extra zero, while options C (5 mcg) and D (0.5 mcg) are incorrect due to miscalculating the conversion factor.
