Question

anonymous · Answer

1 inch = 0.083333 feet, then 27 inches = 2.25 feet.

Scale factor = 2.25 : 36 = 1 : 16

How... what? is it not clear to you? Try to think

anonymous · Answer

There was no equation to solve. Scale factor = Length of model engine/ Length of actual engine. Because of different unit (inch and feet), you must unify to 1 unit only. In this case, I made the unification to unit of "feet". You can search for google: 1 inch = ... feet.

The rest thing is just substitute and divide like I did
