In order to find the fraction of the amount that the discount represents, we just need to divide the discount amount by the total value:
[tex]\frac{40}{2000}[/tex]Now, to simplify this fraction, we can divide the numerator and denominator by 40:
[tex]\frac{40}{2000}=\frac{40\colon40}{2000\colon40}=\frac{1}{50}[/tex]So the discount is 1/50 of the value paid.
