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 millimeters are in 0.75 centimeters?

• A. 7.5 mm
• B. 0.75 mm
• C. 75 mm
• D. 75 cm

Correct answer: C

Rationale: To convert centimeters to millimeters, you need to multiply by 10 since there are 10 millimeters in a centimeter. Therefore, 0.75 centimeters equals 0.75 x 10 = 7.5 millimeters, not 75 millimeters (Choice C). Choice A (7.5 mm) is the correct conversion, while Choice B (0.75 mm) and Choice D (75 cm) are incorrect conversions.

3. Convert 3,540 liters to milliliters (mL).

• A. 354,000 mL
• B. 3,540,000 mL
• C. 35,400 mL
• D. 35,400,000 mL

Correct answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1,000 because there are 1,000 milliliters in 1 liter. Therefore, 3,540 liters × 1,000 = 3,540,000 milliliters. Choices A, C, and D are incorrect because they do not correctly convert liters to milliliters. A, C, and D are off by a factor of 1,000, as they do not account for the conversion factor between liters and milliliters.

4. 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.

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.
