Question

What are the advantages of the representative fraction (RF) over the statement of scale?

Answer 1

Hint:
-The representative fraction and statement of scale are different types of map scales.
-R.F. is generally shown as a fraction.
-Converting an R.F. scale to a verbal scale is extremely easy.

Complete answer:
An R.F. scale is a ratio, or fraction that expresses the mathematical relationship between map and land like 1:24,000 which implies "1 map unit is such as 24,000 land units." As R.F carries no units(inches, centimeters etc) it implies that R.F. scales are compared between different maps.

Advantages of R.F. scale-
-It has universal application. Anyone can find the distance on map whether or not they're aware of the unit of measurement of that country.
-The use of units to express the size makes it the foremost versatile method.
-It is easily convertible.

Additional Information:
How to convert R.F. to Scale:
-To transform the RF scale to the direct scale of the statement, divide the right side of the equation by 100000, to switch the centimetre to the kilometre.
-To convert from the direct scale back to the RF scale, multiply the right side of the equation by 100 000 and change the kilometres to the centimetres.

Note:
i) The ratio of the Earth's size to the generating globe's size is named nominal scale or representative fraction.
ii) Scale- Distance on the map/Distance on the ground.
iii) The only disadvantage of R.F. scale is that it cannot calculate the exact distance as it is represented in fraction form.
