Using Benchmark to Compare Fractions-Example:

Compare each fraction to the benchmark. \(\frac{4}{8}\:\left(\right)\:1\), \(\frac{4}{3}\:\left(\right)\:1\). Then, use this information to compare the two fractions. \(\frac{4}{8}\:\left(\right)\:\frac{4}{3}\)

Solution: First, compare each fraction to the benchmark.

\(\frac{4}{8}\:\left(<\right)\:1\)

\(\frac{4}{3}\:\left(>\right)\:1\)

Now, use this information to compare the two fractions.

\(\frac{4}{8}\:\left(<\right)\:\frac{4}{3}\)
