A benchmark is an easy to work with number. you round fractions to the nearest benchmark and it will be very easy to add. i use 1/4, 1/2, 3/4, 1, 1 1/4, 1 1/2, 1 3/4, 2, 2 1/4, and so on as benchmarks.
No, four sevenths is not a benchmark fraction beacause benchmark fractions are used to estimate and they are easy to picture in your mind. 4 out of seven is not a very good estimate for something and it is not easy to picture in your head. Right?
They are fractions which a user is familiar with or comfortable with, and which can be used to compare a given fraction.
A benchmark is a number used to estimate something. One number or multiple numbers can be used as benchmarks in a mathematical equation.
You just used the word "benchmark" in that sentence..O.o
