Correct Answer: B

Rationale:
To convert a percentage to a decimal, you divide the percentage by 100.
Therefore, 38% as a decimal is 0.38 (38 · 100 = 0.38).
Choice A, 3.8, is incorrect as it is equivalent to 380%.
Choice C, 0.038, is incorrect as it represents 3.8%.
Choice D, 38.0, is incorrect as it is still in percentage form.

Correct Answer: B

Rationale:
To convert ounces to milliliters, we know that 1 ounce is approximately 30 mL.
Therefore, 0.5 ounces would be half of that, which is 15 mL. So, 0.5 oz of perfume is equal to 15 mL.
Choice A (10 mL),
Choice C (20 mL), and
Choice D (25 mL) are incorrect as they do not reflect the accurate conversion from ounces to milliliters.

Correct Answer: A

Rationale: 2 8-oz cups of coffee = 16 oz = 16 30 = 480 mL. 1 16-oz serving of clear soup = 16 30 = 480 mL. 1 pint of water = 16 oz = 480 mL.
Total intake = 480 + 480 + 480 = 1,440 mL. Deficit = 1,440 mL (intake) - 1,000 mL (output) = 440 mL.
Therefore, the deficit in milliliters is 440 mL. The correct answer is A.
Choice B, 540 mL, is incorrect as it miscalculates the total intake.
Choice C, 660 mL, is incorrect as it does not accurately subtract the output from the intake.
Choice D, 760 mL, is incorrect as it overestimates the deficit by not considering the correct total intake and output values.
