1. What is 0.3 ml in tsp?

• A. 0.06 tsp
• B. 0.1 tsp
• C. 0.2 tsp
• D. 0.3 tsp

Correct answer: A

Rationale: To convert milliliters to teaspoons, you can use the conversion factor that there are approximately 5 milliliters in a teaspoon. When you divide 0.3 ml by 5, you get 0.06 teaspoons, which is equivalent to 0.06 tsp. Therefore, the correct answer is A. Choice B, 0.1 tsp, is incorrect because it does not result from the conversion of 0.3 ml to tsp. Choice C, 0.2 tsp, is also incorrect as it does not accurately represent the conversion. Choice D, 0.3 tsp, is the same value as the original quantity in milliliters, which is not the correct conversion to teaspoons.

2. 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.

3. How many grams are in 2 kilograms?

• A. 200 grams
• B. 2000 grams
• C. 20 grams
• D. 2 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, 2 kilograms is equal to 2 x 1000 = 2000 grams. Choice A (200 grams) is incorrect as it represents the value of 0.2 kilograms. Choice C (20 grams) is incorrect as it represents the value of 0.02 kilograms. Choice D (2 grams) is incorrect as it represents the value of 0.002 kilograms.

4. What is 1500 milliliters in liters?

• A. 1.5 liters
• B. 0.15 liters
• C. 15 liters
• D. 0.015 liters

Correct answer: A

Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in 1 liter. Therefore, 1500 milliliters divided by 1000 equals 1.5 liters, making option A the correct answer. Option B, 0.15 liters, is incorrect as it would be the conversion of 150 milliliters. Option C, 15 liters, is incorrect because it would be the conversion of 15,000 milliliters. Option D, 0.015 liters, is incorrect as it would be the conversion of 15 milliliters.

5. What does 'L' stand for in the metric system?

• A. liter
• B. log
• C. link
• D. lever

Correct answer: A

Rationale: In the metric system, 'L' stands for liter, which is the base unit for liquid volume. The other choices are incorrect: 'B' log is not a standard metric unit, 'C' link is a unit of length in the Imperial system, and 'D' lever is not a metric unit but a simple machine.
