Percent Percent is derived from two words  Per meaning for each and cent which is short for 100 (one hundred). Think about a century (100 years) or one cent (penny) because it takes 100 pennies to make 1.00. So, when someone says 35% of the people responding said "Yes" to a question that means that 35 people for each (per) 100 people responded yes. Percent can also be written as a fraction with 100 always in the denominator. so 35% can also be written as 35/100. The decimal form is then = .35 We can write percents in many ways: Example: 25% is equal to:
A convenient method for working with percents has been established and it is called the "Percent Equation." A tool to help you check the "Percent Equation" is presented below. The "Percent Equation" is stated as the following: "A is P percent of B." which can then be set up to solve as such:
