The way that you change a percentage into a decimal is by removing the percent sign off of it (so for example, you have 100%, take off the percent sign and you're left with 100). Next, you move a decimal point 2 places to the left (so you now just have a plain 100--> one decimal step: 10.0--> two decimal steps: 1.00). That is how you transform a percent to a decimal.
