Determine a number of which you want to find 10 percent. For this example, use the number 50, which is the base.
How to Find 10% of a Number
When you find a percent of a number, you get a result that is larger than the number if the percent is greater than 100, or a portion that is smaller than the number if the percent is less than 100. For example 150 percent of 10 equals 15, which is greater than the number, while 50 percent of 10 is 5, which is a smaller portion of the number. The equation to find an amount that is a percentage of a number is "percent x base = amount." "Percent" is the percentage, "base" is the number and "amount" is the result.
