The formula to calculate the percentage is:
\[ X = \frac{Z \times 100}{Y} \]
Where:
Number \(X\) is the fraction out of a hundred of the number \(Z\) with respect to the number \(Y\).
Let's assume the following values:
Using the formula:
\[ X = \frac{2 \times 100}{20} \]
Evaluating:
\[ X = 10 \]
The percentage is 10%.
