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. The metric system is based on what concept?

• A. Multiplication
• B. Powers of 10
• C. Addition
• D. Subtraction

Correct answer: B

Rationale: The metric system is based on powers of 10. This means that units within the system are related by factors of 10, making conversions straightforward by simply shifting the decimal point. The system's simplicity and consistency are derived from this fundamental concept. Choices A, C, and D are incorrect because the metric system's foundation lies in the consistent relationship between units through powers of 10, not through basic arithmetic operations like multiplication, addition, or subtraction.

3. What is the official name of the metric system?

• A. International Measurement System
• B. International System of Units
• C. Metric Unit System
• D. Measurement System of Units

Correct answer: B

Rationale: The official name of the metric system is the International System of Units (SI). The International System of Units is a globally recognized standard for measurement. Choice A, 'International Measurement System,' is incorrect as it does not accurately reflect the official name. Choice C, 'Metric Unit System,' while related to the metric system, is not the precise official name. Choice D, 'Measurement System of Units,' is a mix-up of terms and does not represent the correct official name of the metric system.

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

• A. millimeter
• B. megabyte
• C. millipede
• D. metered

Correct answer: A

Rationale: The correct answer is 'millimeter' (A). 'mm' stands for millimeter, which is equal to one-thousandth of a meter. Choice B, 'megabyte,' is a unit of digital information storage, not a metric system unit. Choice C, 'millipede,' is an arthropod and not a metric unit. Choice D, 'metered,' is not a standard metric unit abbreviation.

5. How many milliliters are in 1.5 liters?

• A. 15 mL
• B. 1,500 mL
• C. 150 mL
• D. 150,000 mL

Correct answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1,000 since there are 1,000 milliliters in a liter. Therefore, 1.5 liters x 1,000 = 1,500 milliliters. Choice A, 15 mL, is incorrect as it represents the conversion of 0.015 liters. Choice C, 150 mL, is incorrect as it represents the conversion of 0.15 liters. Choice D, 150,000 mL, is incorrect as it represents the conversion of 150 liters.
