What is the ratio of words to lines?

1, forcing the front section to be fixed, and the latter term of the ratio is inversely proportional to the ratio.

2. The distance on the map is fixed, and the actual distance is inversely proportional to the scale.

3. Copying a manuscript, the average number of words written per line is inversely proportional to the number of lines.

This is the first answer. I wish you progress!
