Step by Step Solution

In order to solve problem, you must evaluate n₄ / (n₀ * n₁ + n₂ * n₃) * 100.

• n₄ / (n₀ * n₁ + n₂ * n₃) * 100

• Evaluate n₀ * n₁ = 10000

  n₄ / (10000 + n₂ * n₃) * 100

• Evaluate n₂ * n₃ = 12000

  n₄ / (10000 + 12000) * 100

• Evaluate 10000 + 12000 = 22000

  n₄ / 22000 * 100

• Evaluate n₄ / 22000 = 0.09

  0.09 * 100

• Evaluate 0.09 * 100 = 9

  9
• The answer to the problem and the result of n₄ / (n₀ * n₁ + n₂ * n₃) * 100 is 9
