500/800 = 62.5%
A fraction like 500/800, or 62.5%, could describe getting 500 points out of 800 on a test or completing 500 pages of an 800-page reading goal. It might also show how much of a large project is finished, such as packing 500 out of 800 boxes.
To picture 62.5% quickly, think of a little more than half, but clearly less than two-thirds. On a progress bar, it would be a bit past the middle, around five-eighths of the way across.
A common mistake is treating 62.5% as if it were close to 70% or exactly halfway. It is also important to remember that 500/800 describes a ratio, so the meaning depends on what the 500 and 800 represent.
