1. The prefix giga is represented by the following notation ________.

• A. G
• B. m
• C. Gg
• D. g

Correct answer: A

Rationale: The correct answer is A: 'G'. The prefix 'giga' is commonly represented by the letter 'G' and corresponds to a factor of 10^9, which is equivalent to one billion. Choice B, 'm', represents the prefix 'milli', which corresponds to a factor of 10^-3, not 'giga'. Choice C, 'Gg', is incorrect as the prefix 'giga' is represented by a single letter 'G', not 'Gg'. Choice D, 'g', is incorrect as it represents the prefix 'gram' in the International System of Units (SI) and not the prefix 'giga'.

2. What is the equivalent of 255.0 pounds in kilograms (1 kg = 2.205 lbs)?

• A. 115.7 kg
• B. 126.0 kg
• C. 115.8 kg
• D. 115.6 kg

Correct answer: D

Rationale: To convert pounds to kilograms, you need to divide the weight in pounds by 2.205 (1 kg = 2.205 lbs). Therefore, 255.0 pounds divided by 2.205 equals 115.6 kilograms. This results in choice D being the correct answer. Choices A, B, and C are incorrect as they do not reflect the accurate conversion calculation from pounds to kilograms.

3. What is the correct conversion of 35,400 milligrams to grams (g)?

• A. 35.4 g
• B. 35.4 g
• C. 354 g
• D. 354,000 g

Correct answer: B

Rationale: To convert milligrams to grams, you need to divide by 1,000 because there are 1,000 milligrams in a gram. Therefore, 35,400 mg ÷ 1,000 = 35.4 grams. Choice A is incorrect because it does not account for the conversion from milligrams to grams. Choice C is incorrect as it incorrectly drops a zero, leading to an inaccurate conversion. Choice D is incorrect as it incorrectly multiplies instead of dividing, resulting in a significantly larger value than the correct answer.

4. How many pints are in one quart?

• A. 1 pint
• B. 2 pints
• C. 3 pints
• D. 4 pints

Correct answer: B

Rationale: The correct answer is B: 2 pints. There are 2 pints in one quart. A quart is equivalent to 2 pints, so each quart contains 2 pints. Choice A, 1 pint, is incorrect because a quart consists of more than 1 pint. Choice C, 3 pints, and Choice D, 4 pints, are also incorrect as they do not accurately represent the conversion of quarts to pints.

5. What is 0.5 liters expressed in milliliters?

• A. 50 ml
• B. 500 ml
• C. 5 ml
• D. 0.5 ml

Correct answer: B

Rationale: To convert liters to milliliters, you multiply by 1000 since there are 1000 milliliters in a liter. Therefore, 0.5 liters x 1000 = 500 ml. Choice A (50 ml) is incorrect as it would be the conversion of 0.05 liters. Choice C (5 ml) is incorrect as it would be the conversion of 0.005 liters. Choice D (0.5 ml) is incorrect as it is the original measurement in milliliters, not the converted value from liters.
