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.

Correct Answer: B

Rationale: The calculation of 0.4 divided by 40 results in 0.01, which can be expressed as 1/100. This fraction is the correct representation of the division of 0.4 by 40.
Choice A, 1/100, is the correct answer as it accurately reflects the division.

Choices C and D, 1/400 and 1/40000 respectively, do not correctly represent the division operation performed on 0.4 and 40, leading to incorrect results and are therefore not the correct answers.

Correct Answer: A

Rationale: The correct answer is A: 0.3 ml.
To convert milligrams (mg) to milliliters (ml), you typically need the substance's density. However, in many medical contexts, especially with liquid medications similar in density to water, 0.3 mg is commonly assumed to be equivalent to 0.3 ml.
Choice B (3 ml) is incorrect as it is 10 times greater than the correct conversion.
Choice C (30 ml) is incorrect as it is 100 times greater than the correct conversion.
Choice D (0.03 ml) is incorrect as it is one-tenth of the correct conversion.

Correct Answer: B

Rationale: The prefix 'milli' means one-thousandth, which is equivalent to 0.001 of the base unit. For instance, 1 millimeter is equal to 0.001 meters.
Choice A (0.01) is incorrect as it represents one-hundredth, not one-thousandth.
Choice C (0.0001) is incorrect as it signifies ten-thousandth, not one-thousandth.
Choice D (0.00001) is incorrect as it stands for one-hundred-thousandth, not one-thousandth.
