You want to know the answer to this question: what is 10 percent of 20.5? Here is a very simple step-by-step guide to find out.
Step 1: A percentage is a number or ratio expressed as a fraction of 100.
\(10\%\) = \(10 \over 100 \) = \(0.1\)
Step 2: We use the following formula:

• \(X = 20.5\)
• \(P\% = 10\%\) = \(10 \over 100 \) = \(0.1\)
\(Answer: 20.5 \cdot 10\%\) = \(20.5 \cdot 0.1\) = \(2.05\)
• \(X = 20.5\)
• \(P\% = 10\%\) = \(10 \over 100 \) = \(0.1\)
\(Answer: 20.5 \cdot 10\%\) = \(20.5 \cdot 0.1\) = \(2.05\)
