1. How many milliliters are in 0.5 liters?

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

Correct answer: A

Rationale: To convert from liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in a liter. Therefore, 0.5 liters x 1000 = 500 milliliters. This conversion is common in various contexts where different units of volume are used. Choices B, C, and D are incorrect as they do not reflect the correct conversion factor from liters to milliliters.

2. How many ounces are in 2 quarts?

• A. 8 ounces
• B. 32 ounces
• C. 16 ounces
• D. 64 ounces

Correct answer: C

Rationale: To convert quarts to ounces, you need to know that 1 quart is equal to 32 ounces. Therefore, 2 quarts would be 2 x 32 = 64 ounces. The correct answer is not 16 ounces as stated in the original rationale. The correct answer is 64 ounces, which corresponds to 2 quarts. As a result, 'C: 16 ounces' is incorrect. Options A, B, and D are also incorrect as they do not reflect the accurate conversion from quarts to ounces.

3. What is 0.5 x 200?

• A. 100
• B. 50
• C. 150
• D. 200

Correct answer: A

Rationale: To find the product of 0.5 and 200, you multiply the two numbers, which equals 100. The correct answer is A. Choice B, 50, is the result of multiplying 0.5 by 100 instead of 200. Choice C, 150, is the result of adding 0.5 and 200 instead of multiplying them. Choice D, 200, is the second number in the multiplication operation and not the correct product.

4. How many quarts are equivalent to 2 liters?

• A. 1.06 quarts
• B. 0.5 quarts
• C. 2.1 quarts
• D. 4 quarts

Correct answer: A

Rationale: To convert liters to quarts, we know that 1 liter is approximately equal to 1.06 quarts. Therefore, 2 liters would be around 2.12 quarts. However, for practical purposes, it's often rounded to 2.1 quarts. Option A, '1.06 quarts,' is the closest and most accurate approximation. Option B, '0.5 quarts,' is incorrect as it represents half of the actual conversion. Option C, '2.1 quarts,' is close but slightly higher than the actual conversion. Option D, '4 quarts,' is double the correct conversion and is therefore incorrect.

5. What is 0.1 liter converted to milliliters?

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

Correct answer: B

Rationale: To convert 0.1 liter to milliliters, you need to multiply by 1000 because there are 1000 milliliters in a liter. Therefore, 0.1 liter converts to 100 milliliters. Choice A (10 ml) is incorrect as it represents 0.01 liters, not 0.1 liters. Choice C (1000 ml) is incorrect as it represents 1 liter, not 0.1 liters. Choice D (1 ml) is incorrect as it is too small a quantity for 0.1 liters.
