1. What is 0.5 liters in milliliters?

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

Correct answer: B

Rationale: 0.5 liters is equivalent to 500 milliliters. To convert liters to milliliters, you multiply by 1000 since 1 liter equals 1000 milliliters. Therefore, the correct answer is 500 ml (0.5 * 1000 = 500). Choices A, C, and D are incorrect because they do not correctly convert 0.5 liters to milliliters.

2. How many centimeters are in 4 meters?

• A. 40 cm
• B. 400 cm
• C. 4 cm
• D. 0.4 cm

Correct answer: B

Rationale: To convert meters to centimeters, you multiply by 100. In this case, 4 meters x 100 = 400 centimeters. Therefore, the correct answer is 400 cm. Choices A, C, and D are incorrect because they do not correctly convert meters to centimeters.

3. Convert 5,000 milligrams to grams.

• A. 50 grams
• B. 5 grams
• C. 500 grams
• D. 0.05 grams

Correct answer: B

Rationale: To convert milligrams to grams, you need to divide by 1,000 since there are 1,000 milligrams in 1 gram. Therefore, 5,000 milligrams is equal to 5 grams (5,000 ÷ 1,000 = 5). Choice A, '50 grams,' is incorrect as it results from multiplying instead of dividing. Choice C, '500 grams,' is incorrect as it incorrectly multiplies the value. Choice D, '0.05 grams,' is incorrect as it is the result of dividing by 10 instead of 1,000.

4. Convert 0.5 liters to milliliters.

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

Correct answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000 as there are 1000 milliliters in 1 liter. Therefore, when converting 0.5 liters to milliliters, the correct answer is 0.5 x 1000 = 500 ml. Choice A (50 ml) is incorrect because it represents the conversion of 0.05 liters, not 0.5 liters. Choice C (5 ml) is incorrect as it represents the conversion of 0.005 liters. Choice D (0.5 ml) is incorrect as it does not reflect the correct conversion from liters to milliliters.

5. How many meters are in one kilometer?

• A. 100 meters
• B. 1000 meters
• C. 500 meters
• D. 2000 meters

Correct answer: B

Rationale: The correct answer is B: 1000 meters. One kilometer is equivalent to 1000 meters. Therefore, 1000 meters is the accurate conversion from kilometers to meters. Choices A, C, and D are incorrect. Choice A (100 meters) is incorrect as it represents 1/10th of a kilometer. Choice C (500 meters) is incorrect as it is half the value of a kilometer. Choice D (2000 meters) is incorrect as it exceeds the value of a kilometer.
