Correct Answer: A

Rationale: The equation D=2R means that D equals 2 times R, which translates to D being twice the value of R.
Therefore, choice A, 'D is twice as much as R,' is the correct representation of the relationship between D and R.
Choice B, 'R is twice as much as D,' incorrectly reverses the roles of D and R.
Choice C, 'R is two times D,' incorrectly states the relationship between R and D.
Choice D, 'D is two more than R,' does not accurately reflect the relationship presented in the equation.

Correct Answer: C

Rationale:
To convert kilograms to pounds, multiply the weight in kilograms by the conversion factor 2.2 (1 kg = 2.2 lbs).
Therefore, 45 kg * 2.2 lbs/kg = 99 lbs.
Choice A is incorrect because it is a miscalculation.
Choice B is incorrect as it does not reflect the correct conversion.
Choice D is incorrect as it is also a miscalculation of the conversion.

Correct Answer: B

Rationale:
To find the median, we first need to arrange the data set in ascending order: -3, -2, 0, 5, 10. The median is the middle value in the ordered set. As there are 5 numbers, the middle value is the third number, which is 0.
Therefore, the correct answer is 0.
Choice A (10) and
Choice D (2) are not correct because they are not the middle values once the data set is ordered.
Choice C (5) is also incorrect as it is not the middle value in the ordered data set.

Correct Answer: A

Rationale: A proper fraction is characterized by having a numerator smaller than the denominator, while an improper fraction has a numerator larger than the denominator.
Therefore, choice A is correct.
Choice B is incorrect because it states the opposite relationship between the numerator and denominator for proper and improper fractions.
Choice C is incorrect as it describes a fraction where the numerator is equal to the denominator, which is a different concept.
Choice D is incorrect as it associates a numerator being smaller than the denominator with an improper fraction, which is inaccurate.

Correct Answer: A

Rationale: The correct way to find the least common multiple is to list all the multiples of each number and then identify the smallest common multiple.
Choice A is correct because it describes the correct process. Listing factors, as suggested in choice B, helps in finding the greatest common factor, not the least common multiple. Dividing the largest number by the smallest, as mentioned in choice C, does not help find the least common multiple. Multiplying the two numbers together, as stated in choice D, results in their least common multiple when the numbers have no common factors.
