1. Convert 5 kilometers to meters.

• A. 50 meters
• B. 500 meters
• C. 5000 meters
• D. 0.5 meters

Correct answer: C

Rationale: To convert kilometers to meters, you need to multiply by 1000 because there are 1000 meters in 1 kilometer. Therefore, 5 kilometers x 1000 = 5000 meters. Choice A (50 meters) is incorrect because it underestimates the conversion. Choice B (500 meters) is incorrect as it also underestimates the conversion. Choice D (0.5 meters) is incorrect as it incorrectly represents the conversion as less than a kilometer.

2. What is the conversion factor from milliliters to liters?

• A. 0.001 liters
• B. 0.01 liters
• C. 1 liter
• D. 10 liters

Correct answer: A

Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in a liter. Therefore, the correct conversion factor is 0.001 liters (1 liter = 1000 milliliters). Choice B (0.01 liters) is incorrect as it suggests dividing by 100, which is not the correct conversion. Choice C (1 liter) is incorrect because it is the equivalent value in liters, not the conversion factor. Choice D (10 liters) is incorrect as it is not the correct conversion of milliliters to liters.

3. How many grams are in 5 kilograms?

• A. 50 grams
• B. 500 grams
• C. 5000 grams
• D. 5 grams

Correct answer: C

Rationale: To convert kilograms to grams, you need to multiply by 1000 because there are 1000 grams in a kilogram. Therefore, 5 kilograms x 1000 grams/kilogram = 5000 grams. Choices A, B, and D are incorrect because they do not correctly convert kilograms to grams.

4. What is 0.5 L converted to mL?

• A. 500 mL
• B. 50 mL
• C. 5 mL
• D. 0.5 mL

Correct answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters multiplied by 1000 equals 500 milliliters. Choice A, 500 mL, is the correct answer. Choice B, 50 mL, is incorrect as it represents converting 0.05 liters to milliliters. Choice C, 5 mL, is incorrect as it represents converting 0.005 liters to milliliters. Choice D, 0.5 mL, is incorrect as it represents the original amount in milliliters, not the conversion of liters to milliliters.

5. What is 0.004 expressed as a ratio?

• A. 1:250
• B. 4:20
• C. 2:40
• D. 9:20

Correct answer: A

Rationale: The decimal 0.004 can be represented as a ratio of 4/1000, which simplifies to 1/250, making the ratio 1:250. The correct answer is A. Choices B, C, and D are incorrect because they do not reflect the correct conversion of 0.004 into a simplified ratio. Choice B simplifies to 1:5, Choice C simplifies to 1:20, and Choice D simplifies to 9:20, none of which accurately represent the ratio of 0.004.
