Ha, just kidding. Email me your phone number and as soon as my son is home from his Grammy's house, I'll call you and you can explain that to him and if you make him understand........because that went way over my head, like swoooosh...I'll be using my human calculator that sits over there on the sofa, lmao Luke,

Thus, a percentage is how much of something there is expressed in a form of out of one hundred. Thus, if you have a quarter (25 cents) you have 25% of a dollar because you have 25 of the one hundred that you need to make up a dollar. This, of course, gets more confusing when you're talking about something that isn't easily broken into 100 pieces. For example, if you have 20 green army men, and you let your friend borrow 10 of them, what percentage of them do you still have? There are several ways to calculate this, but you could make the original number equal to 100 and then do the same thing to the other equation: 20 * x = 100 10 * x = y 100/20 = x -> 5 10 * 5 = 50 -> Your friend has 50% of your green army men. Percentages can be really hard to do in your head. But we often memorize what some of the basic ones are: 1/2 = 50%, 1/4 = 25%... ~Luke PS.
