1. What is 0.004 as a simplified ratio?

• A. 1:250
• B. 4:35
• C. 7:28
• D. 4:00

Correct answer: A

Rationale: To convert 0.004 to a ratio, we first express it as 4/1000, which simplifies to 1/250. Hence, 0.004 is equivalent to the simplified ratio of 1:250. Choice B, 4:35, is incorrect as it does not reflect the correct conversion. Choice C, 7:28, is incorrect because it does not represent the simplified ratio of 0.004. Choice D, 4:00, is incorrect as it does not simplify to the original decimal value.

2. How many feet are in one mile?

• A. 5000 feet
• B. 5280 feet
• C. 5300 feet
• D. 5500 feet

Correct answer: B

Rationale: The correct answer is B: 5280 feet. One mile is equivalent to 5280 feet. This is a standard conversion that is widely known. Choice A (5000 feet) is incorrect as it is not the exact conversion of a mile. Choice C (5300 feet) and choice D (5500 feet) are also incorrect as they do not represent the accurate conversion from miles to feet.

3. How many milliliters are in 1 liter?

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

Correct answer: C

Rationale: The correct answer is 1,000 milliliters in 1 liter. The conversion from liters to milliliters involves multiplying by 1,000 since 1 liter is equivalent to 1,000 milliliters. Choice A, 10 mL, is incorrect as it represents only a fraction of a liter. Choice B, 100 mL, is also incorrect as it is one-tenth of a liter. Choice D, 10,000 mL, is significantly larger than the correct answer and represents 10 liters, not 1 liter.

4. What is the equivalent of 35.4 centimeters in kilometers (km)?

• A. 0.00354 km
• B. 0.000354 km
• C. 0.00345 km
• D. 0.0345 km

Correct answer: B

Rationale: To convert centimeters to kilometers, you need to divide by 100,000 since there are 100,000 centimeters in a kilometer. Therefore, 35.4 cm ÷ 100,000 = 0.000354 km. Choice A (0.00354 km) is incorrect as it represents dividing by 10,000, not 100,000. Choice C (0.00345 km) is incorrect as the last digit is different from the correct answer. Choice D (0.0345 km) is incorrect as it represents dividing by 1,000, not by 100,000.

5. What does the prefix 'Tera' refer to?

• A. 10^12
• B. 10^9
• C. 10^15
• D. 10^6

Correct answer: A

Rationale: The prefix 'Tera' corresponds to a factor of 10^12, which is equivalent to one trillion. It is commonly used in various fields like data storage to denote large quantities. Choice B, '10^9,' is incorrect as it corresponds to the prefix 'Giga.' Choice C, '10^15,' is incorrect as it corresponds to the prefix 'Peta.' Choice D, '10^6,' is incorrect as it corresponds to the prefix 'Mega.' Therefore, the correct answer is A.
