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