How could you use a benchmark fraction to compare fractions?

You can use a benchmark fraction, such as 1/2, to compare other fractions by determining whether they are greater than, less than, or equal to this benchmark. For instance, if you have the fractions 3/10 and 4/10, you can see that both are less than 1/2, while 5/10 is equal to 1/2. This method simplifies comparison, as you can quickly assess where each fraction stands relative to the benchmark. This approach is particularly useful for visualizing fractions on a number line.
