1. Convert 25 millimeters to centimeters.

• A. 250 cm
• B. 25 cm
• C. 2.5 mm
• D. 25 mm

Correct answer: D

Rationale: To convert millimeters to centimeters, you need to divide by 10 because there are 10 millimeters in one centimeter. Therefore, 25 millimeters is equal to 25/10 = 2.5 centimeters, making choice D the correct answer. Choice A (250 cm) is incorrect as it incorrectly multiplies instead of dividing by 10. Choice B (25 cm) is also incorrect as it doesn't convert millimeters to centimeters. Choice C (2.5 mm) is incorrect as it provides the measurement in millimeters rather than centimeters.

2. How many centimeters are in one meter?

• A. 1/10 cm
• B. 100 cm
• C. 10 cm
• D. 1000 cm

Correct answer: B

Rationale: The correct answer is B: 100 cm. One meter is equivalent to 100 centimeters. This conversion is based on the metric system, where the prefix 'centi-' represents one hundredth. Choices A, C, and D are incorrect because they do not accurately reflect the conversion of meters to centimeters. Choice A, '1/10 cm,' is incorrect as it represents a fraction of a centimeter, not the full conversion from meters to centimeters. Choice C, '10 cm,' is incorrect as it represents the conversion from decimeters to centimeters, not meters to centimeters. Choice D, '1000 cm,' is incorrect as it represents the conversion from meters to millimeters, not centimeters.

3. What is the base unit for liquid volume in the metric system?

• A. Milliliters
• B. Liters
• C. Gallons
• D. Liters

Correct answer: B

Rationale: The correct answer is B: Liters. In the metric system, liters are the base unit for liquid volume. Milliliters, though a metric unit, are a smaller unit of volume and not the base unit. Gallons, on the other hand, are part of the imperial system and not a metric unit for volume. Option D is a duplicate of option B, making it incorrect.

4. What is 0.02 as a ratio?

• A. 1:50
• B. 1:20
• C. 2:100
• D. 4:20

Correct answer: C

Rationale: To convert 0.02 to a ratio, you need to express it as a fraction. 0.02 is equivalent to 2/100. Simplifying this fraction gives you 1/50. So, the correct ratio for 0.02 is 1:50. Choice A is correct because it accurately represents the ratio of 0.02. Choices B, C, and D are incorrect: B is not the simplified form of 0.02, C simplifies to 1:50, not 2:40, and D is not the correct simplified ratio for 0.02.

5. How many liters (L) are equal to 1 kiloliter?

• A. 100 liters
• B. 1,000 liters
• C. 10 liters
• D. 10,000 liters

Correct answer: B

Rationale: To convert kiloliters to liters, you multiply by 1,000. Therefore, 1 kiloliter × 1,000 = 1,000 liters. Choice A (100 liters) is incorrect because it represents only 1/10th of a kiloliter. Choice C (10 liters) is incorrect as it represents only 1/100th of a kiloliter. Choice D (10,000 liters) is incorrect as it is 10 times bigger than a kiloliter.
