Error 2: Wrong Number of Segments (Denominator)

Definition

When representing a fraction a/b on a number line, a wrong number of segments occurs if the interval from 0 to 1 (or any whole-number span) is divided into a number of equal subintervals that is not equal to b.

The total count of equal segments must match the denominator for the fraction to be correct.

Example

If showing 3/4, but the segment from 0 to 1 is split into 3 or 5 equal parts instead of 4, we consider this error type to be the “wrong number of segments”, regardless of whether the parts are all equal in size.
