[1] Assuming you ment the number 1720: 1720 seconds as a percentage DEPENDS on a percentage of what you want? If you want 1720 as a %age of minutes that would be: (1720/60) * 100 = 2866.6666666666666666666666666667% of a Minute If you want 1720 as a %age of hours what would be: (1720/3600) * 100 = 47.777777777777777777777777777778% of an Hour [2] Assuming you meant 17 as a percentage and 20 as a percentage: 17 and 20 seconds as a percentage DEPENDS on a percentage of what you want? If you want 17 or 20 as a %age of minutes that would be: [For 17] (17/60) * 100 = 28.333333333333333333333333333333% of a Minute [For 20] (20/60) * 100 = 33.333333333333333333333333333333% of a Minute If you want 17 or 20 as a %age of hours what would be: [17] (17/3600) * 100 = 0.47222222222222222222222222222222% of an Hour [20] (20/3600) * 100 = 0.55555555555555555555555555555556% of an Hour If you wanted any of those a a percentage of any period of time follow this equation structure: A/B*100 (A=Amount to want as a %age, B=Bounty/Total Possible Amount) Example: If you wanted them as a %age of a day you would divide 17 or 20 or 1720 by how many seconds there are in a day, 86400, and then times that by 100 to give you a %age.
