1. Convert 0.004 to a ratio.

• A. 1:250
• B. 4:200
• C. 2:400
• D. 9:200

Correct answer: A

Rationale: To convert 0.004 to a ratio, we can express it as 4/1000, which simplifies to 1/250. Therefore, the correct ratio is 1:250. Choice B (4:200) is incorrect as it simplifies to 1:50, not 1:250. Choice C (2:400) simplifies to 1:200, which is also incorrect. Choice D (9:200) simplifies to a ratio greater than 1:1, which is not equivalent to 1:250.

2. The metric prefix of Tera is abbreviated as T- and has a value of 10^12. What does Tera mean numerically?

• A. 10^6
• B. 10^9
• C. 10^12
• D. 10^3

Correct answer: C

Rationale: The correct answer is C: 10^12. Tera represents a numerical value of 10^12, which is equivalent to one trillion. It is commonly used in computing and other fields to denote large-scale measurements. Choice A, 10^6, is incorrect as it corresponds to the metric prefix 'Mega.' Choice B, 10^9, is incorrect and corresponds to the metric prefix 'Giga.' Choice D, 10^3, is incorrect and corresponds to the metric prefix 'Kilo.' Therefore, the correct interpretation of the metric prefix Tera is 10^12.

3. What is 0.004 as a ratio?

• A. 5:10
• B. 1:250
• C. 7:28
• D. 4:00

Correct answer: B

Rationale: To convert 0.004 to a ratio, first express it as a fraction by writing it as 4/1000. Simplifying this fraction gives 1/250. Therefore, 0.004 as a ratio is 1:250. Choice A (5:10) simplifies to 1:2, not equivalent to 0.004. Choice C (7:28) does not simplify to a value close to 0.004. Choice D (4:00) is not a valid ratio representation of 0.004.

4. How many liters (L) are equal to 1 kiloliter?

• A. 100 liters
• B. 1,000 liters
• C. 10 liters
• D. 10,000 liters

Correct answer: B

Rationale: To convert kiloliters to liters, you multiply by 1,000. Therefore, 1 kiloliter × 1,000 = 1,000 liters. Choice A (100 liters) is incorrect because it represents only 1/10th of a kiloliter. Choice C (10 liters) is incorrect as it represents only 1/100th of a kiloliter. Choice D (10,000 liters) is incorrect as it is 10 times bigger than a kiloliter.

5. 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.
