Hello aspirant,
Representative Fraction or R.F. is defined as the ratio of distance on the map to the actual distance on the ground and is generally expressed in the form of 1 along with a : (colon) or / (right slash) and a number then, as the one represents the numerator in the fraction, colon is the division operator and the number is the denominator. For example- 1:40,000 or 1/40,000.
