1. 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.

2. What is 0.5 liters expressed in milliliters?

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

Correct answer: B

Rationale: To convert liters to milliliters, you multiply by 1000 since there are 1000 milliliters in a liter. Therefore, 0.5 liters x 1000 = 500 ml. Choice A (50 ml) is incorrect as it would be the conversion of 0.05 liters. Choice C (5 ml) is incorrect as it would be the conversion of 0.005 liters. Choice D (0.5 ml) is incorrect as it is the original measurement in milliliters, not the converted value from liters.

3. How many ounces are in one pint?

• A. 12 ounces
• B. 16 ounces
• C. 8 ounces
• D. 20 ounces

Correct answer: B

Rationale: The correct answer is B: 16 ounces. One pint is equivalent to 16 ounces. This is a common conversion in cooking and baking measurements. Choice A (12 ounces) is incorrect because it does not represent the correct conversion of pints to ounces. Choice C (8 ounces) is incorrect as it is not the correct equivalent for a pint. Choice D (20 ounces) is incorrect as it overestimates the number of ounces in a pint. Understanding these conversions is essential when following recipes or working with liquid measurements in various contexts.

4. The metric system is based on what concept?

• A. Multiplication
• B. Powers of 10
• C. Addition
• D. Subtraction

Correct answer: B

Rationale: The metric system is based on powers of 10. This means that units within the system are related by factors of 10, making conversions straightforward by simply shifting the decimal point. The system's simplicity and consistency are derived from this fundamental concept. Choices A, C, and D are incorrect because the metric system's foundation lies in the consistent relationship between units through powers of 10, not through basic arithmetic operations like multiplication, addition, or subtraction.

5. Convert 0.75 kilograms to grams.

• A. 75 grams
• B. 750 grams
• C. 7,500 grams
• D. 75,000 grams

Correct answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in a kilogram. Therefore, 0.75 kilograms is equal to 0.75 x 1000 = 750 grams. Choices A, C, and D are incorrect as they incorrectly place the decimal point and do not reflect the correct conversion from kilograms to grams.
