Efficiency as a percent is output/input * 100%
12000/15000 * 100% = 80% efficiency which makes sense, because it takes more work (input) than it give out (output). So the efficiency should be less than 100%.

How do you find the input power in the electric efficiency formula if you have the output power and the efficiency percent?
Output equals efficiency times input; in formula, Ot = Ef x In and so In = Ot/Ef. To calculate the original input, divide the output by the efficiency.
How does the output work compare to the input work for a machine that has an efficiency equal to 100 percent?
If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.
The ratio of output compaired to in input?
It is the efficiency of a machine.
The ratio of output work to input work is?
efficiency
Efficiency can be express mathematically as?
Efficiency = Output/Input. This is usually expressed as a percentage but may be given in the form of a ratio.Another AnswerEfficiency is output power divided by input power, normally expressed as a percentage.
What means work output divided by work input?
input force x input distance > output force x output distance -Novanet

What is the ratio of output to input?
efficiency
What is efficiency and how is it calculated?
The efficiency is output divided by input.
Which math ratio represents efficiency?
Efficiency = Output/Input.
How does the output work compare to the input work for a machine that has an efficiency equal to 100 percent?
If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.
What is the formula for efficiency?
Output/Input * 100= %
What is the ratio of the output to the input force?
It is the efficiency.
Efficiency is a comparison of?
Efficiency is output power divide by input power.
The output work of a machine compared to it input work is the of the machine?
Output(input), or O(i)
What is the term for the comparison of input and output work of a machine?
Sounds like you are asking about "mechanical advantage"...
How is the efficiency of a machine calculated?
Efficiency = useful output power / input power
