# Error 3: Wrong Number of Segments Chosen (Numerator)

## Definition
When representing a/b on a number line, this error occurs after the line has been correctly partitioned into b equal subintervals per unit, but the number of consecutive subintervals selected, shaded, or hopped from 0 is not a.

## Example
For 3/4, the unit is split into four equal parts (which is done correctly), but the student shades two parts, showing 2/4 instead of 3/4.
