On the number line, is Desmond correct? Explain why or why not.

The number line between 0 and 1 is divided into 6 equal segments. The dot is located on the 4th mark from 0.
Therefore, the dot represents the fraction $\frac{4}{6}$.

$\frac{2}{12}$ represents the dot.
To compare $\frac{2}{12}$ with $\frac{4}{6}$, we can simplify $\frac{2}{12}$:

Since $\frac{1}{6} \neq \frac{4}{6}$, $\frac{2}{12}$ does not represent the dot.

$\frac{3}{6}$ represents the dot.
Comparing $\frac{3}{6}$ with $\frac{4}{6}$, we see that they are not equal.
Since $\frac{3}{6} \neq \frac{4}{6}$, $\frac{3}{6}$ does not represent the dot.

Desmond is incorrect. The dot on the number line represents $\frac{4}{6}$. Neither $\frac{2}{12}$ (which simplifies to $\frac{1}{6}$) nor $\frac{3}{6}$ is equivalent to $\frac{4}{6}$.

Desmond is incorrect.
