84/80 = 105%
A value like 84/80, or 105%, can show up when something goes slightly beyond its original target. For example, a student might finish 105% of an assignment goal, or a store might sell 105% of the number of tickets it expected to sell.
You can picture 84/80 as one whole amount plus a small extra piece. Since the top and bottom numbers are close, estimate it as just over 100%, with the extra amount being about one-twentieth of the whole.
A common mistake is thinking 105% must be much larger than 100%. In reality, it is only 5% above the starting amount, so it represents a small increase rather than a dramatic change.
