Multiply each side by 10/3.
$$1 \text{ inch}=\frac{35}{12}=2.92 \text{ miles} $$

If you multiply each side by 8/7 then the number of miles would be one and you would have some sort of a weird number for map length.

The former solution is standard practice, 1 unit of map lenth equals so many physical miles.
