Correct Answer: A

Rationale:
To find the product of 375 and 2.3, multiply them: 375 2.3 = 862.5. When multiplying by 2.3, it is important to shift the decimal point appropriately after performing the calculation.
Choice A, 862.5, is the correct answer.
Choice B, 750, is incorrect because it is the result of multiplying 375 by 2.
Choice C, 225.75, is incorrect as it appears to be the result of multiplying the numbers in the wrong order.
Choice D, 1125, is incorrect as it seems to be the result of multiplying 375 by 3 instead of 2.3.

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.

Correct Answer: A

Rationale:
To find the sum, you add the numbers 3.7, 7.289, and 4 together. 3.7 + 7.289 + 4 equals 14.989. The correct answer is 14.989 because it includes all decimal places from the sum of the numbers provided.
Choice B (5.226) is incorrect as it doesn't account for the sum of the given numbers.
Choice C (15.0) is incorrect as it rounds the sum to the nearest whole number, losing the decimal precision.
Choice D (5.012) is incorrect as it doesn't reflect the correct sum of the decimal numbers.

Rationale:
To find the result of multiplying 7.2 by 0.34, multiply these two numbers: 7.2 x 0.34 = 2.448. The correct answer is 2.448.
Choice A, 14.12, is incorrect as it seems to be the sum of the two numbers.
Choice B, 0.234, is incorrect as it is much smaller than the expected result.
Choice C, 7.64, is incorrect as it is the result of adding the two numbers rather than multiplying them.
