INDICATES the ratio between the NUMBER of units on the map to the number of units on the ground or a representative fraction (RF) is the ratio of distance on the map to distance on the ground.\({\RM{Representative\;fraction\;}}\left( {{\rm{R}}.{\rm{F}}.} \RIGHT) = \frac{{Distance\;on\;the\;map}}{{Distance\;on\;the\;ground}}\;\)\({\left( {RF} \right)^2} = \left( {\frac{{AREA\;on\;the\;map}}{{Area\;on\;the\;ground}}} \right)\)
