1. Convert 0.29 pounds to ounces.

• A. 2.9 ounces
• B. 4.64 ounces
• C. 29 ounces
• D. 46.4 ounces

Correct answer: B

Rationale: To convert pounds to ounces, you need to know that there are 16 ounces in a pound. Multiplying 0.29 pounds by 16 gives you 4.64 ounces. Therefore, the correct answer is B. Choice A (2.9 ounces) is incorrect as it doesn't consider the conversion factor of 16 ounces per pound. Choice C (29 ounces) and Choice D (46.4 ounces) are incorrect because they incorrectly interpret the conversion from pounds to ounces.

2. What is 0.125 as a fraction?

• A. 1/8
• B. 1/4
• C. 1/2
• D. 1/16

Correct answer: A

Rationale: To convert 0.125 to a fraction, we write it as 125/1000. Simplifying by dividing both the numerator and denominator by 125 gives us 1/8. Therefore, choice A (1/8) is the correct answer. Choice B (1/4) is incorrect as it represents 0.25, not 0.125. Choice C (1/2) is incorrect as it represents 0.5, not 0.125. Choice D (1/16) is incorrect as it represents 0.0625, not 0.125.

3. How many milliliters are in 1.5 liters?

• A. 15 mL
• B. 1,500 mL
• C. 150 mL
• D. 150,000 mL

Correct answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1,000 since there are 1,000 milliliters in a liter. Therefore, 1.5 liters x 1,000 = 1,500 milliliters. Choice A, 15 mL, is incorrect as it represents the conversion of 0.015 liters. Choice C, 150 mL, is incorrect as it represents the conversion of 0.15 liters. Choice D, 150,000 mL, is incorrect as it represents the conversion of 150 liters.

4. How many ounces are in one gallon?

• A. 64 ounces
• B. 128 ounces
• C. 100 ounces
• D. 150 ounces

Correct answer: B

Rationale: The correct answer is B: 128 ounces. One gallon is equivalent to 128 ounces. This conversion relationship is commonly used in cooking, baking, and various liquid measurements. Choice A (64 ounces) is incorrect as it represents half the amount of a gallon. Choice C (100 ounces) and Choice D (150 ounces) are also incorrect, as they do not accurately reflect the conversion of a gallon to ounces.

5. What is 0.05 mcg in mg?

• A. 0.00005 mg
• B. 0.0005 mg
• C. 0.005 mg
• D. 0.05 mg

Correct answer: A

Rationale: To convert micrograms (mcg) to milligrams (mg), you need to divide by 1000. Therefore, 0.05 mcg equals 0.00005 mg. This conversion is crucial in the medical field to ensure accurate dosing. Choice B, 0.0005 mg, is incorrect as it represents 0.5 mcg. Choice C, 0.005 mg, is the equivalent of 5 mcg. Choice D, 0.05 mg, actually represents 50 mcg. It's important to pay attention to decimal placement and unit conversions to avoid medication errors.
