The term 5 percent written in decimal form is 0.05. According to Syracuse University, converting a percent to a decimal involves dividing the percent by 100, which is the equivalent to moving the decimal point two places to the left.
To change a decimal into a percent, the above process is reversed. For example, the number 0.35 is equal to 35 percent. This is calculated by multiplying the decimal by 100, or simply by moving the decimal point two places to the right and adding the percent sign.
This method shows that 100 percent is equal to the number one. Thus, a number in decimal form such as 2.25 is the same as 225 percent.
