243/240 = 101.25%
A value like 243/240, or 101.25%, can show up when something goes slightly over its target. For example, a student might score 243 points out of a possible 240 because of bonus questions, or a store might sell 243 items when it expected to sell 240.
You can picture it as one whole amount plus a tiny extra piece. Since 101.25% is only 1.25% above 100%, it is just a little more than the full target—about one extra part for every 80 parts.
A common mistake is to treat 101.25% as if it were only 1.25% of the original amount. It actually represents the entire original amount, or 100%, plus an additional 1.25%.
