To change a decimal to a percent, multiply the decimal by 100. Example: 1.5 x 100 = 150%
To change a percent into a decimal divide it by 100 for example 75% = 0.75
It is done by: (0.2-0.1)/0.1 times 100 = 100% change or increase
When you have a percent, you move the decimal over two places to the left to get the answer. For example: 5.0 would be 0.05
Before you ever start to work on a problem with a percent in it, stop and think what 'percent' means, and change the percent to a number that you can do arithmetic with. 'Percent' means 'hundredth'. To change a percent to a real number, either divide it by 100, or move the decimal point two places to the left. (Same thing.) 37 percent means 0.37 50 percent means 0.50 84 percent means 0.84 20.2 percent means 0.202 . 3/5 means 0.6 20.2 percent of 3/5 means (0.202 x 0.6) = 0.1212
