Place fractions on a number line

A fraction on a number line represents a point determined by partitioning each whole-number interval into equal parts, with the denominator naming the number of parts and the numerator naming how many parts from zero. This includes locating fractions less than, equal to, and greater than one, including mixed numbers, and recognizing equivalent fractions at the same point; it does not extend to negative fractions, arbitrary real-number generalizations, or advanced denominator systems.

Detailed Explanation: Place fractions on a number line

A fraction tells you where to place a point on a number line:

The denominator tells how many equal parts to divide each whole into.
The numerator tells how many of those parts to count from $0$ .

Example: Locate $\frac{7}{4}$

The denominator is $4$ , so divide each whole-number interval into $4$ equal parts.
Count $7$ $7$ parts from $0$ $0$ :
- After $4$ parts, you reach $1$ .
- Count $3$ more parts to reach $\frac{7}{4}$ .
The point is at $1\frac{3}{4}$ , because

\frac{7}{4}=1\frac{3}{4}.

0\quad \frac14\quad \frac24\quad \frac34\quad 1\quad \frac54\quad \frac64\quad \frac74\quad 2

So, $\frac{7}{4}$ is the point three fourths of the way from $1$ to $2$ .

Remember: if the numerator is smaller than the denominator, the fraction is between $0$ and $1$ . If the numerator equals the denominator, the fraction equals $1$ . If the numerator is larger, the fraction is greater than $1$ .
