Which of the following representative fractions would indicate the largest scale map? Options: • 1:1 • 1:0 • 1:1,000,000 • 1:24,000

Answers

Final Answer:

The largest scale map is indicated by the representative fraction 1:1. Option A is correct.

Explanation:

In cartography, the representative fraction (RF) of a map indicates the scale of the map, specifically the ratio between a distance on the map and the corresponding distance on the Earth's surface. A larger RF value means a larger scale map, which represents smaller areas with more detail.

Now, let's compare the given options:

1. 1:1 - This RF means that one unit on the map represents one unit on the ground, essentially a one-to-one scale. It doesn't get any larger than this, so this is the largest scale possible.

2. 1:0 - This doesn't make sense in cartography because you cannot represent the Earth's surface with zero on one side of the ratio. It's an invalid option.

3. 1:1,000,000 - This RF indicates that one unit on the map represents one million units on the ground. This is a much smaller scale compared to 1:1, so it represents a much larger area with less detail.

4. 1:24,000 - This RF means that one unit on the map represents 24,000 units on the ground. While this is a larger scale than 1:1,000,000, it is still smaller than 1:1, which is the largest scale.

In summary, the largest scale map is represented by 1:1. Option A is the answer.

Answer:

The representative fraction (RF) of a map indicates the scale of the map. In a representative fraction, the first number represents a unit of measurement on the map, and the second number represents the corresponding unit of measurement in the real world.

Among the options provided, a larger scale map would have a smaller second number because it means that one unit of measurement on the map represents a smaller unit of measurement in the real world. So, the largest scale map in the given options is:

1:24,000

In this case, 1 unit on the map represents 24,000 units in the real world, indicating a very detailed and large-scale representation of the area.

Which one of the following mathematical statements is true?A. 28 + 0 = 0
B. 0 ÷ 28 = 0
C. 28 – 0 = 0
D. 28 ÷ 0 = 0

Answers

B. 0 ÷ 28 = 0

Is the mathematical statement that is true.

Rule of ZERO. Zero(0) can be a numerator with non-zero denominator. Its overall value is equal to 0.

Rule of ZERO. A fraction with a denominator of ZERO is not a legal fraction. This is because the overall value of a number divided by zero is undefined.

28 + 0 = 28 not 0.
28 - 0 = 28 not 0.
28 ÷ 0 = ERROR! not 0. value is undefined
