Recognize benchmark fractions

Benchmark fractions are familiar reference quantities—especially 0, 1/2, and 1, with 1/4 and 3/4 when useful—that support interpreting, locating, estimating, and comparing fractions on a number line. This understanding includes recognizing equivalent forms, such as 2/4 and 0.5 for 1/2, and avoids the misconception that numerator or denominator size alone determines a fraction’s value; formal approximation with arbitrary percentages is beyond this scope.

Detailed Explanation: Recognize benchmark fractions

Benchmark fractions are familiar fractions that help you understand where another fraction belongs. The most useful benchmarks are $0$ , $\frac12$ , and $1$ . You can also use $\frac14$ and $\frac34$ .

Example: Locate $\frac78$ on a number line and decide which benchmark it is closest to.

Choose helpful benchmarks.

Use $\frac12$ and $1$ :

\frac12=\frac48 \qquad\text{and}\qquad 1=\frac88

Compare $\frac78$ with the benchmarks.

Since

\frac48<\frac78<\frac88,

$\frac78$ is between $\frac12$ and $1$ .

Decide where it belongs.

$\frac78$ is only $\frac18$ less than $1$ , so it is very close to $1$ . On a number line, place it just before $1$ :

0 \qquad\qquad \frac12=\frac48 \qquad\qquad \frac78 \qquad 1=\frac88

Remember that the numerator or denominator alone does not tell you the fraction’s value. Compare the fraction with familiar benchmarks instead.
