The correct equation for a machine's efficiency is:
Efficiency = (output energy / input energy) × 100
This equation measures how effectively a machine converts input energy into output energy, expressed as a percentage.
So, the first response is the correct choice:
Efficiency = (output energy / input energy) × 100
