279/450 = 62%
A value like 279/450, or 62%, could describe a quiz score, the portion of a class that submitted an assignment, or the percentage of shoppers who chose a certain product. It shows that a little more than half of the total meets the condition being measured.
To picture 62% quickly, imagine a group of 100 items with 62 highlighted. You can also think of it as being close to three-fifths, though it is slightly higher than that.
A common mistake is to treat 62% as if it means 62 out of every 10 items instead of 62 out of every 100. It is also easy to assume that 62% is nearly all of something, when it actually leaves 38% uncounted.
