Question

energy output = 25 units
energy input = 100 units
energy efficiency = 0.25
what is the energy efficiency percentage?
0.25 × 100 = ?%
energy efficiency × 100 = energy efficiency %
hint: enter a number.

Explanation:

Step1: Identify the formula

To convert energy efficiency (a decimal) to a percentage, we use the formula: \( \text{Energy Efficiency \%} = \text{Energy Efficiency} \times 100 \)

Step2: Substitute the value

We know the energy efficiency is \( 0.25 \). Substitute this into the formula: \( 0.25 \times 100 \)

Step3: Calculate the result

\( 0.25 \times 100 = 25 \)

Answer:

25
