Question

energy output = 25 units
energy input = 100 units
energy efficiency = 0.25
now, if you want to calculate energy efficiency percentage, what value should be substituted into the green box?
? × 100 = energy efficiency %
energy efficiency × 100 = energy efficiency %
hint: enter a number.

Explanation:

Step1: Recall the formula for percentage conversion

To convert a decimal to a percentage, we multiply the decimal by \(100\). Here, the energy efficiency is given as a decimal (\(0.25\)).

Step2: Substitute the value

Since \(Energy\ Efficiency\times100 = Energy\ Efficiency\%\), and \(Energy\ Efficiency = 0.25\), the value to be substituted into the box is \(0.25\).

Answer:

\(0.25\)
