Fraction Comparison: Identifying Parts Greater Than 2/5

To solve the problem, we need to determine which option displays parts painted more than $\frac{2}{5}$.

• Step 1: Each option shows an arrangement divided into 5 boxes. We seek parts painted red exceeding $\frac{2}{5}$.

• Step 2: Analyze each visual:
  -- Option 1, 1 block painted out of 5, fraction = $\frac{1}{5}$.
  -- Option 2, 2 out of 5 blocks painted, fraction = $\frac{2}{5}$.
  -- Option 3, 3 blocks painted out of 5, fraction = $\frac{3}{5}$.
  -- Option 4, 1 block painted out of 5, fraction = $\frac{1}{5}$.

• Step 3: Compare $\frac{3}{5}$ in Option 3 with $\frac{2}{5}$.

Therefore, the only choice where the painted part is greater than $\frac{2}{5}$ is Option 3.
