1 in 20 means for every 1" (or 1cm) on the map represents 20" (or 20cm) in real life. Thus a scale of 1:63360 is 1" representing 63,360 inches, which is 1 mile. So 1" on a map is 1 mile in real life.

Map scale in representative fraction form is expressed as a ratio or fraction, such as 1:25,000. This ratio shows the relationship between a distance on the map and the actual distance on the Earth's surface. For example, a scale of 1:25,000 means that 1 unit of measurement on the map represents 25,000 of the same units in the real world.
In a map scale where the numerator is always 1, it is called a verbal scale. This type of scale expresses the relationship between distance on the map and actual distance on the ground in words, such as "1 inch equals 10 miles."
To convert map measurements to actual distance, measure the scale distance on the map and multiply by the denominator of the scale (the larger number in the ratio). e.g. two cm on a 1:25000 map equals 2x25000 = 50,000 cm or 500 meters.
A representative scale refers to the ratio of a distance on a map to the corresponding distance on the Earth's surface. It helps users understand the relationship between distances on a map and in reality. It is often depicted as a scale bar or ratio.
A map scale in social studies refers to the relationship between distances on a map and the corresponding distances on the Earth's surface. It helps users to understand the size and relative distances of features on a map. Different types of map scales exist, such as verbal, graphic, and representative fractions, with each providing a different way to represent the scale of the map.
To convert the direct statement scale to a representative fraction (RF) scale, you need to invert the ratio. In this case, the conversion would be 1:102922 (rounded to the nearest whole number). This means that 1 unit on the map represents 102,922 units on the ground.
