To convert a percentage to a decimal, you would remove the percent and move the decimal point two places to the left.
65% = 0.65
To convert a percentage to a fraction, you would remove the percent and place the number over 1. Then, you would multiply the top and bottom by 10 for every number after the decimal point... And, finally, reduce it.
65% = 65/100
65/100 = 13/20
I hope this helps!
