Correct Answer: A

Rationale:
To convert liters to kiloliters, divide by 1000 since there are 1000 liters in a kiloliter.
Therefore, 147 liters = 0.147 kiloliters.
Choice B is incorrect as it incorrectly moves the decimal point.

Choices C and D are significantly larger than the correct answer, indicating an incorrect conversion factor used.

Correct Answer: B

Rationale: The correct answer is B: 'Positive number.' When you subtract one negative number from another negative number, the result can be a positive number. For example, the difference between -5 and -3 is 2, which is a positive number.
Choice A, 'Negative number,' is incorrect because the result of subtracting two negative numbers can be positive.
Choice C, 'Zero,' is incorrect because the difference between two negative numbers is not always zero.
Choice D, 'Not enough information,' is incorrect because there is enough information to determine that the difference between two negative numbers can be a positive number.

Correct Answer: C

Rationale:
To determine the smallest decimal, we look at the digits after the decimal point. In this case, 2.002 is the smallest because it has the least value in the thousandths place.
Choice A, 2.22, has a higher value in the hundredths place making it larger.
Choice B, 2.02, has a higher value in the hundredths place compared to 2.002.
Choice D, 2.2, is larger than 2.002 as it has a higher value in the tenths place.

Correct Answer: D

Rationale:
To find the fourth vertex of a parallelogram, we can use the properties of a parallelogram. Opposite sides of a parallelogram are parallel and equal in length.
Therefore, we can determine the fourth vertex by extending the line formed by the first two points. If we extend the line from (1, 2) to (3, 4), we find that it has a slope of 1. This means that extending the line from (3, 4) by the same slope will give us the fourth vertex. By adding 2 units to both x and y coordinates of (5, 6), we get (7, 8) as the coordinates of the fourth vertex.
Therefore, the correct answer is (7, 8).

Choices A, B, and C are incorrect as they do not satisfy the properties of a parallelogram and the given coordinate points.

Correct Answer: A

Rationale:
To convert fluid ounces to gallons, you need to divide the number of fluid ounces by the number of fluid ounces in a gallon. Since there are 128 fluid ounces in a gallon, to find out how many gallons are in 1,000 fluid ounces, you divide 1,000 by 128. The correct calculation is 1,000 / 128 = 7.8125 gallons.
Therefore, the correct answer is A.

Choices B, C, and D are incorrect as they do not accurately represent the conversion from fluid ounces to gallons.
