1. What is 0.5 liters equivalent to?

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

Correct answer: A

Rationale: 0.5 liters is equivalent to 500 milliliters. This conversion is straightforward because 1 liter equals 1000 milliliters. Choice A is correct because it accurately converts 0.5 liters into milliliters. Choices B, C, and D are incorrect as they do not correctly convert the given volume into milliliters.

2. What is the equivalent of 500 milliliters in liters?

• A. 0.05 liters
• B. 0.5 liters
• C. 5 liters
• D. 50 liters

Correct answer: B

Rationale: To convert milliliters to liters, you need to divide by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 500 milliliters divided by 1000 equals 0.5 liters. Choice A (0.05 liters) is incorrect because it represents 50 milliliters, not 500 milliliters. Choice C (5 liters) and Choice D (50 liters) are both incorrect as they are higher values and do not accurately represent the conversion of 500 milliliters to liters.

3. How many millimeters are in 5 centimeters?

• A. 50 mm
• B. 500 mm
• C. 5 mm
• D. 500 cm

Correct answer: B

Rationale: To convert centimeters to millimeters, you multiply by 10 since there are 10 millimeters in a centimeter. Therefore, 5 centimeters x 10 = 50 millimeters, making choice A the correct answer. Choice C, '5 mm,' is incorrect as it represents the original quantity in millimeters. Choice D, '500 cm,' is incorrect as it converts the centimeters to centimeters instead of millimeters.

4. What is 0.04 liters converted to milliliters?

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

Correct answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1,000 since there are 1,000 milliliters in a liter. So, to convert 0.04 liters to milliliters, you would multiply 0.04 by 1,000, giving you 40 milliliters. This means that choice A, '40 ml', is the correct answer. Choices B, C, and D are incorrect because they do not correctly convert liters to milliliters. Choice B, '4 ml', is incorrect as it is 10 times smaller than the correct conversion. Choice C, '400 ml', is incorrect as it is 10 times larger than the correct conversion. Choice D, '0.4 ml', is incorrect as it is one-tenth of the correct conversion.

5. 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.
