To solve the problem $300:(20\cdot8)-(13+200)$, follow these steps:

• Step 1: Evaluate the multiplication $20 \cdot 8$.
  $20 \cdot 8 = 160$
• Step 2: Perform the division $300:160$.
  $300 \div 160 = 1.875$
• Step 3: Calculate the addition inside the parentheses $13 + 200$.
  $13 + 200 = 213$
• Step 4: Subtract the result of the addition from the division.
  $1.875 - 213 = -211.125$
• Step 5: Convert the decimal to a fraction, if necessary.
  Since $-211.125$ is equivalent to $-211\frac{1}{8}$.

Therefore, the solution to the problem is $-211\frac{1}{8}$, which corresponds to choice 3.
