To calculate percentages using the PERCENTAGE function in Excel, follow these steps:
Start by entering a number in a cell, which will represent the whole or total value.
In another cell, enter the desired percentage as a decimal (e.g., 0.25 for 25%, 0.5 for 50%, etc.).
In a new cell, use the formula "=PERCENTAGE(total_value, percentage)" to calculate the percentage. Replace "total_value" with the cell reference or the actual value of the total, and "percentage" with the cell reference or the actual value of the percentage.
For example, if the total value is in cell A1 and the percentage is in cell B1, you would use the formula "=PERCENTAGE(A1, B1)" to calculate the percentage. The result will be displayed as a decimal.
The calculated percentage will now appear in the cell according to the specified formatting.
