Understanding Percentages
A percentage is a fraction represented out of one hundred. The symbol “%” denotes a percentage. For example, 50% means 50 out of every 100, which can be expressed as the fraction 50/100 or the decimal 0.50. Percentages are widely used to express proportions, ratios, and changes in quantities.
Calculating Percentages
To calculate a percentage, we follow a simple formula:
Percentage = (Part / Whole) x 100
Where:
- Part: The value we want to express as a percentage.
- Whole: The total value or the base amount.
Let’s illustrate this formula with an example. Suppose we want to find what percentage 20 represents of 100.
Percentage = (20 / 100) x 100 = 20%
Therefore, 20 is 20 percent of 100. (See Also: 11 Is What Percent of 22? Find Out Now)

Now, let’s apply this understanding to our main question: “7 is what percent of 56?”
In this case:
- Part = 7
- Whole = 56
Substituting these values into our percentage formula:
Percentage = (7 / 56) x 100
