(0.6 ÷ 0.7)*100= 85.7%.

Why no one has manually solved this 0.6/0.7 to get 0.857.
06/10 ÷ 07/10.
06/10 * 10/07 cross multiplication will cancel both 10.
06/07 = 0.857,
For efficiency, %age multiply it with 100.
= 85.7%.
06/10 ÷ 07/10.
06/10 * 10/07 cross multiplication will cancel both 10.
06/07 = 0.857,
For efficiency, %age multiply it with 100.
= 85.7%.

eff=output power/input power * 100.
So output power is 0.6w and input power is 0.7 watt.
0.6/0.7 * 100 = 85.7%.
So output power is 0.6w and input power is 0.7 watt.
0.6/0.7 * 100 = 85.7%.

Normally the efficiency formula is;
Efficiency =outputpower/inputpower * 100.
Efficiency =outputpower/inputpower * 100.

Efficiency=Otput/Input X 100.
= 85.7%.
= 85.7%.

Efficiency = output/input.
= .6/.7.
= .857.
% = .857 * 100.
= 85.7%.
= .6/.7.
= .857.
% = .857 * 100.
= 85.7%.
