747/744 = ≈100.4%
Rounded to 2 decimal places.
A value like 747/744 can show up when a measurement is just slightly higher than its target, such as a package weighing a little over the labeled amount. It represents about 100.4%, so the actual amount is only a bit more than the expected 100%.
To picture it quickly, imagine 744 as one full group and 747 as that same group plus 3 extra items. Since the difference is small, you can estimate the fraction as just over 100%, rather than thinking of it as a much larger amount.
A common mistake is to treat 100.4% as 0.4% or as 4% more than the original amount. It means the full amount is 100%, with an additional 0.4 percentage points, so the increase is very small.
