1. Convert 345,000 millimeters to centimeters (cm).

• A. 34,500 cm
• B. 3,450 cm
• C. 345,000 cm
• D. 345,000,000 cm

Correct answer: B

Rationale: To convert millimeters to centimeters, you need to divide by 10 since there are 10 millimeters in 1 centimeter. Therefore, 345,000 mm ÷ 10 = 34,500 cm. Choice A is incorrect because it is a factor of 10 higher than the correct answer. Choice C is incorrect because it represents the original quantity in centimeters, not the converted value. Choice D is incorrect as it erroneously multiplies the millimeters by 1,000 instead of dividing by 10 to convert to centimeters.

2. What is the result of multiplying 0.15 by 3?

• A. 0.05
• B. 0.15
• C. 0.45
• D. 0.45

Correct answer: C

Rationale: The correct answer is C: 0.45. To find the result of multiplying 0.15 by 3, you simply multiply the two numbers together, which gives you 0.45. Choice A (0.05) is incorrect as it is the result of dividing 0.15 by 3 instead of multiplying. Choice B (0.15) is the original number being multiplied and not the result. Choice D (0.45) is the same as the correct answer but is repeated for redundancy.

3. Which of the following is equal to 0.13 inches?

• A. 0.013 inches
• B. 1.3 inches
• C. 0.13 inches
• D. 13 inches

Correct answer: C

Rationale: The correct answer is C: 0.13 inches. When converting decimals to inches, the value remains the same. Choice A, 0.013 inches, represents a smaller value than 0.13 inches as it has an extra zero. Choice B, 1.3 inches, is incorrect as it is a larger value than 0.13 inches. Choice D, 13 inches, is significantly larger than 0.13 inches, making it an incorrect conversion.

4. 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.

5. What is the correct formula to convert Fahrenheit to Celsius?

• A. F = (C × 9/5) + 32
• B. C = (F - 32) × 5/9
• C. C = (F - 32) × 9/5
• D. F = (C + 32) × 5/9

Correct answer: B

Rationale: The correct formula to convert Fahrenheit to Celsius is C = (F - 32) × 5/9. This formula is derived from the relationship between the two temperature scales. The incorrect choices can be ruled out as follows: A. F = (C × 9/5) + 32 - This formula is used to convert Celsius to Fahrenheit. C. C = (F - 32) × 9/5 - This formula incorrectly multiplies by 9/5 instead of dividing. D. F = (C + 32) × 5/9 - This formula does not subtract the constant 32 from the Fahrenheit value.
