2% as a fraction will be 2/100, but simplified it will be 1/50, 20% as a fraction will be 2/10, but simplified it will be 1/5. 85% as a fraction will be 85/100, but simplified will be 17/20.

[tex]\frac{2}{100}[/tex]
You would then want to simplify, dividing the numerator and denominator by 2,
[tex]\frac{1}{50}[/tex]
