1. Convert 5,000 milligrams to grams.

• A. 50 grams
• B. 5 grams
• C. 500 grams
• D. 0.05 grams

Correct answer: B

Rationale: To convert milligrams to grams, you need to divide by 1,000 since there are 1,000 milligrams in 1 gram. Therefore, 5,000 milligrams is equal to 5 grams (5,000 ÷ 1,000 = 5). Choice A, '50 grams,' is incorrect as it results from multiplying instead of dividing. Choice C, '500 grams,' is incorrect as it incorrectly multiplies the value. Choice D, '0.05 grams,' is incorrect as it is the result of dividing by 10 instead of 1,000.

2. Convert 34.5 grams to kilograms (kg).

• A. 3.45 kg
• B. 34.5 kg
• C. 345 kg
• D. 3.45 grams

Correct answer: A

Rationale: To convert grams to kilograms, divide by 1,000 since there are 1,000 grams in a kilogram. Therefore, 34.5 grams ÷ 1,000 = 0.0345 kilograms. The correct answer is 3.45 kg (not 3.45 grams, which is the amount given in the initial question). Choices B and C are incorrect as they do not involve the conversion from grams to kilograms. Choice D is also incorrect as it presents the value in grams instead of kilograms.

3. What is 0.6 liters converted to milliliters?

• A. 600 ml
• B. 60 ml
• C. 6 ml
• D. 0.6 ml

Correct answer: A

Rationale: To convert 0.6 liters to milliliters, you need to multiply by 1,000 since there are 1,000 milliliters in a liter. Therefore, 0.6 liters equals 600 milliliters. Choice B (60 ml) is incorrect as it is a conversion of 0.06 liters, not 0.6 liters. Choice C (6 ml) is incorrect as it represents a conversion of 0.006 liters, not 0.6 liters. Choice D (0.6 ml) is incorrect as it is the original amount in milliliters, not the converted amount from liters.

4. 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.

5. 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.
