Benchmarks should not be used to compare 6/7 and 7/8.
To compare these two fractions, it's often helpful to convert them to a common denominator or to decimal form. However, using benchmarks, such as knowing that 1/2, 1/3, or 3/4 can help give a rough estimate of where these fractions fall relative to whole numbers or common fractions, can sometimes aid in understanding their values. For example:
- 6/7 is slightly less than 1.
- 7/8 is also slightly less than 1, but closer than 6/7.
In this case, you can conclude that 7/8 is greater than 6/7.
