1. Convert 250 milliliters to liters.

• A. 25 liters
• B. 0.25 liters
• C. 2.5 liters
• D. 0.025 liters

Correct answer: B

Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in a liter. Therefore, 250 milliliters is equal to 250/1000 = 0.25 liters. Choice A, 25 liters, is incorrect as it is a magnitude higher than the correct answer. Choice C, 2.5 liters, is also incorrect as it is 10 times greater than the correct conversion. Choice D, 0.025 liters, is incorrect as it is a magnitude lower than the correct conversion.

2. 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.

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. Convert 0.1 liter to milliliters. What is the equivalent volume?

• A. 1 ml
• B. 10 ml
• C. 100 ml
• D. 1000 ml

Correct answer: C

Rationale: To convert liters to milliliters, you need to multiply the number of liters by 1,000 because there are 1,000 milliliters in a liter. Therefore, 0.1 liter is equal to 100 milliliters. Choice A (1 ml) is incorrect because it represents the conversion of 0.01 liters, not 0.1 liters. Choice B (10 ml) is incorrect as it also represents the conversion of 0.01 liters. Choice D (1000 ml) is incorrect as it represents the conversion of 1 liter, not 0.1 liter.

5. Convert 0.875 to a fraction,

• A. 7\8
• B. 8\7
• C. 3\4
• D. 9\10

Correct answer: A

Rationale: To convert 0.875 to a fraction, express it as 875\10000. Simplifying this fraction by dividing both the numerator and denominator by 125 results in 7\80.
