To change a PERCENT to a DECIMAL: Get rid of the % sign, and move the decimal point 2 places to the left (which, technically speaking, is dividing by 100). Remember that in a percent, if the decimal point is not shown, it always is after the number, because, for example, 6% is the same thing as 6.0%
82% = 0.82
7% = 0.07
1% = 0.01
To change a DECIMAL to a FRACTION: Read the decimal aloud properly. Don't say, for example, "two point 5", but use tenths, hundredths, thousandths, etc. Let's say you have 0.25. That is read as "twenty-five hundredths." Since you said "hundredths," the fraction is 25 over 100. Simplify the fraction from there, which in this case turns into 1/4.
0.82 = eighty-two hundredths = 82/100 (then simplify to 41/50)
0.07 = seven hundredths = 7/100
0.01 = one hundredth = 1/100
Each place to the right of the decimal has a different name (tenths, hundredths, etc.) Here they are in order, going from the decimal point to the right:
...and on and on and on.... You get the idea :)
Sorry that was so insanely long, hope it makes sense now!

Move the decimal for the first one. 82% = .82.
To put it into a fraction, divide it by 100 since 82% means 82/100 here.
