Well write it in decimal form first : 65.0
Then divide it by 100 because when you make a decimal into a percent you multiply it by 100, so : 0.65.
Now put it in fraction form. *Remember the decimal places. Eg : tenths, hundreds* : 65/100
Now simplify *You can take away zeros too, but this doesn't share zeros so don't* : 65/100 -->13/20
13/20 is your fraction. Hope I helped! 13/20 = 65%
