1. Convert 354,000 millimeters to meters (m).

• A. 354 m
• B. 354 m
• C. 354,000 km
• D. 35,400 m

Correct answer: B

Rationale: To convert millimeters to meters, you need to divide by 1,000 since there are 1,000 millimeters in a meter. Therefore, 354,000 mm ÷ 1,000 = 354 meters. Choice A, '354 m,' is correct as it represents the converted value. Choice C, '354,000 km,' is incorrect as it suggests converting to kilometers instead of meters. Choice D, '35,400 m,' is incorrect as it is not the result of the correct conversion calculation.

2. How many quarts are in 1 gallon?

• A. 2 quarts
• B. 4 quarts
• C. 3 quarts
• D. 1 quart

Correct answer: B

Rationale: The correct answer is B: 4 quarts. There are 4 quarts in 1 gallon. This conversion is based on the fact that 1 gallon is equivalent to 4 quarts. Choice A is incorrect as 2 quarts are half of a gallon, not a whole gallon. Choice C is incorrect as 3 quarts is less than a gallon. Choice D is incorrect as it represents only one quart, whereas the question asks for the quantity in a gallon.

3. Convert 0.0345 kilograms to grams (g).

• A. 3.45 grams
• B. 34.5 grams
• C. 345 grams
• D. 3450 grams

Correct answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1,000 since 1 kilogram is equal to 1,000 grams. Therefore, 0.0345 kg multiplied by 1,000 equals 34.5 grams. Choices A, C, and D are incorrect because they do not correctly convert kilograms to grams. A states 3.45 grams, which is off by a factor of 10. C and D overestimate the conversion by considering the decimal point in the original value as a whole number. Hence, the correct answer is B, 34.5 grams.

4. What does 'mg' stand for in the metric system?

• A. microgram
• B. milligram
• C. gigabyte
• D. megagram

Correct answer: B

Rationale: 'mg' stands for milligram, which is equal to 1/1,000th of a gram. In the metric system, 'microgram' (choice A) is represented by 'mcg', 'gigabyte' (choice C) is a unit of digital information storage, and 'megagram' (choice D) is equivalent to a metric ton.

5. How many milliliters are in 0.5 liters?

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

Correct answer: A

Rationale: To convert from liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in a liter. Therefore, 0.5 liters x 1000 = 500 milliliters. This conversion is common in various contexts where different units of volume are used. Choices B, C, and D are incorrect as they do not reflect the correct conversion factor from liters to milliliters.
