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 0.5 liters converted 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 the number of liters by 1000 because there are 1000 milliliters in 1 liter. Therefore, 0.5 liters converts to 500 milliliters. Choice A (50 ml) is incorrect as it is the result of multiplying by 10 instead of 1000. Choice C (5 ml) is incorrect as it is the result of dividing by 10 instead of multiplying by 1000. Choice D (0.5 ml) is incorrect as it represents the original quantity in milliliters, not the conversion from liters.

3. What does the prefix 'centi' mean?

• A. 0.1
• B. 0.01
• C. 0.001
• D. 1

Correct answer: B

Rationale: The prefix 'centi' means 0.01, which is one-hundredth of the base unit. For example, 1 centimeter is equal to 0.01 meters. Choice A (0.1) is incorrect as it represents 'deci,' which means one-tenth. Choice C (0.001) is incorrect as it represents 'milli,' which means one-thousandth. Choice D (1) is incorrect as it is not a valid interpretation of the prefix 'centi.' Therefore, the correct answer is B.

4. What is equivalent to 1 L?

• A. 1 kilogram
• B. 1 quart
• C. 1 milliliter
• D. 1000 milliliters

Correct answer: D

Rationale: 1 liter is equivalent to 1000 milliliters. This conversion is based on the fact that 1 liter equals 1000 milliliters, a standard metric relationship. Choice A is incorrect because a kilogram is a unit of mass, not volume. Choice B, 1 quart, is a non-metric unit of volume and is not equivalent to 1 liter. Choice C, 1 milliliter, is too small to be equivalent to 1 liter; it takes 1000 milliliters to make up 1 liter.

5. 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.
