• A. 20 ml
• B. 30 ml
• C. 40 ml
• D. 50 ml

Correct answer: B

Rationale: The correct answer is B: 30 ml. 1 ounce is equivalent to 30 milliliters. This conversion is a common one in many contexts involving liquid measurements. Choice A (20 ml), Choice C (40 ml), and Choice D (50 ml) are incorrect conversions and do not represent the accurate conversion between ounces and milliliters.

2. What is 0.5 multiplied by 20?

• A. 10
• B. 15
• C. 20
• D. 25

Correct answer: A

Rationale: To find the product of 0.5 and 20, you multiply them together. 0.5 x 20 = 10. This calculation involves multiplying a decimal (0.5) by a whole number (20). Choice A, '10', is the correct answer. Choice B, '15', is incorrect as it does not accurately represent the result of multiplying 0.5 by 20. Choices C and D, '20' and '25', are also incorrect as they do not reflect the correct calculation. This question assesses your ability to perform basic arithmetic operations involving decimals and whole numbers.

3. What does 'cm' stand for in the metric system?

• B. cubic meter
• C. cord
• D. centi

Correct answer: A

Rationale: In the metric system, 'cm' stands for centimeter, which is a unit of length equal to 1/100th of a meter. The correct answer is 'centimeter' (A). Choice B, 'cubic meter,' is a unit of volume, not length. Choice C, 'cord,' is not a standard metric unit. Choice D, 'centi,' is a prefix meaning one-hundredth, but 'cm' specifically stands for centimeter, not just the prefix.

4. What is 0.09 liters in milliliters when converted?

• A. 0.09 ml
• B. 90 ml
• C. 900 ml

Choice A, 0.09 ml, is incorrect as it represents the original volume in milliliters. Choices C and D, 900 ml and 9 ml, are incorrect as they miscalculate the conversion from liters to milliliters.

5. What is 0.5 liters equivalent to?

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

Correct answer: A
