71/80 = 88.75%
A value like 71/80, or 88.75%, could describe a student answering 71 out of 80 questions correctly on a test. It might also represent a phone battery that is nearly full or the percentage of a project completed.
To picture 71/80 quickly, think of a whole divided into 80 equal parts, with only 9 parts missing. It is a little less than 90%, so you can estimate it as being close to nine-tenths of the whole.
A common mistake is to treat 88.75% as 88.75 points instead of understanding it as a portion of a total. The value is also not the same as 71%, because the denominator is 80 rather than 100.
