Fractions are compared as numbers representing parts of the same whole, using benchmarks such as 0, 1/2, and 1 and locating fractions on a number line or interpreting them in equal-part models. The reasoning includes determining whether a fraction is less than, equal to, or greater than a benchmark—for example, recognizing that 3/8 is less than 1/2 and 5/6 is greater than 1/2—rather than assuming a larger denominator means a larger fraction; general procedures such as cross-multiplication are not included.

To compare fractions, think about where each one belongs compared with a benchmark such as , , or .
Step 1: Compare with .
One-half of 8 equal parts is 4 parts:
Since 3 parts is less than 4 parts,
Step 2: Compare with .
One-half of 6 equal parts is 3 parts:
Since 5 parts is more than 3 parts,
Step 3: Compare the fractions.
is less than , while is greater than . Therefore,
The denominator tells how many equal parts make the whole, so a larger denominator does not automatically mean a larger fraction. Use benchmarks to decide where each fraction is located.
