The easiest way to convert a percentage into a fraction is to consider the % symbol to be a pronumeral which has a value of 1/100.
This gives us
30.% = 30. x 1/100 = 30/1 x 1/100 = 30/100
where 30. was rewritten as 30/1 and the two fractions were multiplied together by simply multiplying their numerators and denominators.
Now we need to multiply the numerator and denominator of the fraction by 1 to get rid of the decimal :
30/100 = 30/100 x 1/1 = 30/100
In order to find the simplest form of the fraction 30/100 we cancel out the greatest common divisor of 30 and 100, which is 10 :
30/100 = 3/10
So the final answer is
30.% = 3/10

Well, 30% is 30% of 100%. So the fraction would be 30 over 100. Simple as that. To put the fraction the lowest way possible, just divide both the numerator (top number) and denominator (bottom number) by 10. Giving you a fraction of 3 over 10.

See that little zero, the slash and the second little zero? (%) That is symbolic of a fraction. Per cent means per 100, so 30% means thirty parts of a hundred. 30/100. Strike the last zero in the numerator (top number) and strike the last zero in the denominator (the bottom number) and you get 3/10, or three-tenths.
25% = 25/100 (Twenty-five hundredths) Divide the numerator by 25 and the denominator by 25 and you get 1/4, one-fourth!
72% - 72/100 (seventy-two hundredths) Divide, say 2 into 72 and 100 and you get 36/50, and that's another even number so you can try dividing 4 into 72 and 100 and get 16/25 (sixteen twenty-fifths)
Easy huh?!

Technically speaking, 30% already IS a fraction:
30% = 30 per centum
30% = 30 . / . . 100
Per centum is an ancient way of saying per hundred. Being abbreviated to percent it has managed to remain more popular than per hundred when Latin fell out of use as the universal language of Western scholars.

rewrite x% as x/100 and simplify.
So:
30% = 30/100 = 3/10

% means out of one-hundred so you take the number of the percent and put it over 100, 100 being the denominator.
