Remember, to find percentages, we can use the ratio 


  part        percent
-------- =  ----------
  whole        100



Since 300 is the "part", 450 is the "whole", this gives the ratio: 300%2F450=x%2F100

300%2F450=x%2F100 Start with the given ratio


%28300%2F450%29%2A100=x Multiply both sides by 100


30000%2F450=x Multiply


200%2F3=x Simplify



So our answer is x=200%2F3 which is roughly 66.67


Now subtract this percentage from 100 to get

100-66.67=33.33

So the percent of discount is 33.33%
