I am not sure what you mean.
If this is for a scale drawing where 60cm of drawing represents 1m of real life measurement then
the scale is 60:100
this can be simplified down to 6:10 or 3:5
If the scale drawing measures 6cm you could mult this by 100/60 to get the real life equivalent of 10cm
If the scale drawing measures 2.6cm you could mult this by 100/60 to get the real life equivalent of
$${\mathtt{2.6}}{\mathtt{\,\times\,}}\left({\frac{{\mathtt{100}}}{{\mathtt{60}}}}\right) = {\frac{{\mathtt{13}}}{{\mathtt{3}}}} = {\mathtt{4.333\: \!333\: \!333\: \!333\: \!333\: \!3}}$$
that is 4.33cm
does that help?
