126/125 = 100.8%
A value like 126/125 can show up when something is just slightly more than the whole amount. For example, a store might sell 126 items when it expected to sell 125, or a machine might produce 126 units instead of its 125-unit target, reaching 100.8% of the goal.
You can picture 126/125 as one complete group of 125 plus just 1 extra part. Since that extra part is small compared with the whole, a quick estimate is “about 101%,” with the exact value being only a little above 100%.
A common mistake is to treat 100.8% as if it were 0.8% because of the decimal. It actually means 100% plus another 0.8%, so the amount is slightly greater than the original whole, not less than 1% of it.
