1. **Problem:** draw the fraction $rac{2}{4}$ like a pie. 2. A fraction shows parts of a whole. The bottom number tells how many equal slices the pie has, and the top number tells how many slices are shaded. 3. For $rac{2}{4}$, the pie is split into $4$ equal parts and $2$ of those parts are shaded. 4. This fraction can also be simplified: $$\frac{2}{4}=\frac{\cancel{2}^{1}}{\cancel{4}^{2}}=\frac{1}{2}$$ 5. So the picture shows half of the pie shaded. 6. **Final answer:** $rac{2}{4}$ means $2$ shaded slices out of $4$ equal slices, which is the same as $rac{1}{2}$.
