Question

energy output = 25 units
energy input = 100 units
what is the energy efficiency?
25 ÷ 100 =
energy output ÷ energy input = energy efficiency

Explanation:

Step1: Perform division

$$25\div100 = \frac{25}{100}$$

Step2: Simplify fraction

$$\frac{25}{100}=\frac{25\div25}{100\div25}=\frac{1}{4}=0.25$$

Answer:

$0.25$
