1. What does the prefix 'centi' mean?

• A. 0.1
• B. 0.01
• C. 0.001
• D. 1

Correct answer: B

Rationale: The prefix 'centi' means 0.01, which is one-hundredth of the base unit. For example, 1 centimeter is equal to 0.01 meters. Choice A (0.1) is incorrect as it represents 'deci,' which means one-tenth. Choice C (0.001) is incorrect as it represents 'milli,' which means one-thousandth. Choice D (1) is incorrect as it is not a valid interpretation of the prefix 'centi.' Therefore, the correct answer is B.

2. 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.

3. What is the equivalent of 0.3 milliliters?

• A. 0.03 ml
• B. 0.3 ml
• C. 3 ml
• D. 30 ml

Correct answer: B

Rationale: 0.3 milliliters is equivalent to 0.3 ml. This is a precise measurement commonly used in medical settings for administering small doses of liquid medication. It is important to understand and recognize the decimal point placement when converting between milliliters and other volume units. Choice A (0.03 ml) is incorrect as it represents a smaller amount than 0.3 ml. Choice C (3 ml) and Choice D (30 ml) are also incorrect as they are larger measurements and do not match the given amount of 0.3 ml.

4. How many ounces are in 2 quarts?

• A. 8 ounces
• B. 32 ounces
• C. 16 ounces
• D. 64 ounces

Correct answer: C

Rationale: To convert quarts to ounces, you need to know that 1 quart is equal to 32 ounces. Therefore, 2 quarts would be 2 x 32 = 64 ounces. The correct answer is not 16 ounces as stated in the original rationale. The correct answer is 64 ounces, which corresponds to 2 quarts. As a result, 'C: 16 ounces' is incorrect. Options A, B, and D are also incorrect as they do not reflect the accurate conversion from quarts to ounces.

5. What is 0.45 liters in milliliters?

• A. 450 ml
• B. 45 ml
• C. 4.5 ml
• D. 0.45 ml

Correct answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter equals 1000 milliliters. Therefore, 0.45 liters is equivalent to 450 milliliters. Choice B, 45 ml, is incorrect as it represents the conversion of 0.045 liters to milliliters. Choice C, 4.5 ml, is incorrect as it represents the conversion of 0.0045 liters to milliliters. Choice D, 0.45 ml, is incorrect as it is the initial quantity in milliliters and not the result of the conversion.
