. When we want to understand how much one number is in relation to another, we can express it as a percentage.
The Calculation
To find out what percentage 4 is of 20, we can use the formula:

In this case, the "Part" is 4 and the "Whole" is 20. Plugging in these numbers:
[ \text{Percentage} = \left( \frac{4}{20} \right) \times 100 ]
Step-by-Step Breakdown

Divide the Part by the Whole: [ \frac{4}{20} = 0.20 ]
-
Multiply by 100 to get the Percentage: [ 0.20 \times 100 = 20% ]
