Percentages as Fractions

As well as writing percentages in decimal form, it's also possible to think of them as fractions. Starting with 1% (one hundredth) we can write 1% = 1/100.

Similarly we can write any percentage as a fraction out of a hundred, but we can often simplify the fraction:

Percentage	Equivalent Fraction	Simplest Fraction
80%	8/10	4/5
50%	5/10	1/2
25%	25/100	1/4
33·3%	333/1000	1/3

Note that in the last example, 1/3 would be a recurring decimal.
