Correct Answer: C

Rationale: Since 1 gram (g) equals 1000 milligrams (mg) and 1 g = 1 teaspoon (tsp), the prescribed 1000 mg is equal to 1 tsp.
Therefore, you will give 1 teaspoon of the Benadryl liquid.

Choices A, B, and D are incorrect because they do not correspond to the correct conversion of 1 g to 1 tsp, which is essential in solving this dosage calculation.

Correct Answer: A

Rationale:
To find the cost of 1 book, divide the total cost by the number of books: $4 / 3 = $1.33 per book.
To determine the cost of 6 books, multiply the cost per book by 6: $1.33 * 6 = $8.
Therefore, purchasing 6 books will cost $8.
Choice B, $12, is incorrect as it incorrectly doubles the cost of 3 books.
Choice C, $6, is incorrect as it is half the cost of 3 books.
Choice D, $10, is incorrect as it does not accurately calculate the cost of 6 books based on the given information.

Correct Answer: A

Rationale:
To calculate the number of diapers needed in a year with 6 diaper changes per day, multiply the daily diaper changes (6) by the days in a year (365): 6 x 365 = 2190 diapers required. This calculation ensures an ample supply of diapers for maintaining the infant's hygiene and comfort. The other choices are incorrect because they do not accurately account for the number of diaper changes per day multiplied by the days in a year.
Choice B (2100 diapers) is too low, while choices C (2160 diapers) and D (2140 diapers) are too high based on the calculation. Understanding the frequency and quantity of diaper changes is crucial for supporting the infant's health and well-being.
Therefore, the correct answer is 2190 diapers.

Correct Answer: A

Rationale: The correct answer is A: 3000 meters.
To convert kilometers to meters, you need to know that there are 1000 meters in 1 kilometer.
Therefore, to find the number of meters in 3 kilometers, you multiply 3 by 1000, resulting in 3000 meters.
Choice B, 2000 meters, is incorrect as it doesn't account for the correct conversion factor.
Choice C, 3500 meters, and
Choice D, 2500 meters, are also incorrect as they provide inaccurate conversions.

Correct Answer: B

Rationale:
To convert yards to feet, you multiply by 3, as 1 yard is equal to 3 feet.
Therefore, 3 yards equals 3 x 3 = 9 feet.
Choice A (18 feet) is incorrect because it multiplies by 2 instead of 3.
Choice C (12 feet) is incorrect as it multiplies by 4 instead of 3.
Choice D (27 feet) is incorrect as it multiplies by 9 instead of 3.
