1. Convert 0.6 liters to milliliters.

• A. 60 ml
• B. 600 ml
• C. 6 ml
• D. 6000 ml

Correct answer: B

Rationale: To convert 0.6 liters to milliliters, you need to multiply by 1000 since 1 liter equals 1000 milliliters. 0.6 * 1000 = 600 ml, which is the correct answer. Choice A (60 ml) is incorrect because it represents 0.06 liters. Choice C (6 ml) is incorrect as it would be the milliliter equivalent for 0.006 liters. Choice D (6000 ml) is incorrect as it would be the milliliter equivalent for 6 liters.

2. What is the base unit for volume of a solid in the metric system?

• A. cubic meters
• B. meters cubed
• C. grams
• D. centimeters

Correct answer: A

Rationale: The correct answer is 'cubic meters' (A) which is the base unit for volume of a solid in the metric system. Volume is measured in cubic units (length × width × height) for solids. Choice B, 'meters cubed,' is not the standard way to express volume in the metric system. Choices C and D, 'grams' and 'centimeters,' are units of mass and length respectively, not volume.

3. What is 0.2 rounded to the nearest tenth?

• A. 0.1
• B. 0.2
• C. 0.3
• D. 0.25

Correct answer: B

Rationale: The decimal 0.2 is already at the nearest tenth, so it does not need to be rounded. Rounding to the nearest tenth means keeping one decimal place, which is already the case with 0.2. Therefore, the correct answer is 0.2, as it is already at the specified rounding point. Choices A, C, and D are incorrect because they represent values that are not the result of rounding 0.2 to the nearest tenth. 0.1 is rounding down, 0.3 is rounding up, and 0.25 is not the nearest tenth of 0.2.

4. What is 0.004 as a simplified ratio?

• A. 1:250
• B. 4:35
• C. 7:28
• D. 4:00

Correct answer: A

Rationale: To convert 0.004 to a ratio, we first express it as 4/1000, which simplifies to 1/250. Hence, 0.004 is equivalent to the simplified ratio of 1:250. Choice B, 4:35, is incorrect as it does not reflect the correct conversion. Choice C, 7:28, is incorrect because it does not represent the simplified ratio of 0.004. Choice D, 4:00, is incorrect as it does not simplify to the original decimal value.

5. What is 0.5 liters to milliliters?

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

Correct answer: A

Rationale: The question asks for the conversion of 0.5 liters to milliliters. The correct answer is 500 ml, which is derived from the standard conversion factor where 1 liter is equal to 1000 milliliters. Choice B, 50 ml, is incorrect as it represents the conversion of 0.05 liters to milliliters. Choice C, 5 ml, is incorrect as it corresponds to the conversion of 0.005 liters to milliliters. Choice D, 0.5 ml, is incorrect as it is the same value given in the question but in milliliters.
