That's a little confusing. If you want to find 5 percent of any number, multiply that number by .05 If you're saying that a number has been increased by 5 percent and you want to find the original number, divide the increased number by 1.05 Let's do it with easy numbers. 5 percent of 100 is 5 because 100 x .05 = 5 105 is 5 percent more than 100 because 105 divided by 1.05 = 100
5% equals 5/100, or 1/20. So 5 percent of 4000 is 4000/20 = 200
