Work Out Percentages

Learning to work out percentages is a necessary thing no matter what your station in life. When you go to a restaurant, you will need to leave a tip and not knowing the correct amount can be costly. You don't want to pay too much (resulting in your being broke) and you don't want to pay too little (resulting in a disgruntled waitress). The easy way out is to carry a tip calculator-a small card that fits in your wallet and tells you how much 15 or 20% is for any amount, but it's nice to know how percentages are calculated also. So if you don't have a calculator and you need to calculate a tip on your bill, what should you do? You can grab a pen and scrap paper. Let's say your bill is 26.97. Simply round up to 27 and multiply by .2 (for 20%). 27 x .2=5.40. Is there an easier way? Yes! An easy rule of thumb is that your 20% tip will be $2.00 out of each $10. So if your bill is $26.97, it is closest to $30 and $2 out of each $10 would be $2 x 3 = $6.00 tip. A $6 tip is right on target and a smidgen of generosity, but it's still not over the top. Ten percent of something is even easier to figure since it is just looking at the first few numbers and moving the decimal place one spot to the left. For example 10% of $2.00 would be 20 cents, and 10% of $96.27 would be $9.62 And you were able to figure that out all in your head without having a piece of paper. http://hubpages.com/hub/How-To-Work-Out-Percentages-Easily
