Example: {{Fac Ratio|Steel mill|4/7|Coal mine|1/7|Iron mine|ratio=
1 Iron mine : 1 Coal mine : 1 Steel mill
1 Iron mine : 1.75 Steel mill
1 Coal mine : 7 Steel mill
|fully=4 Coal mine and 1 Iron mine|fullynum=7}}
gives

You need 4/7 of 1 Coal mine, 1/7 of 1 Iron mine to maintain this factory.
To become fewer remains and a perfect production, you will need 4 Coal mine and 1 Iron mine for 7 Steel mill but remember it may vary..

Minimum: 1 Iron mine : 1 Coal mine : 1 Steel mill
