Step by Step Solution

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

• (n₁ + n₁) / (n₁ / n₀ + n₁ / n₂)

• Evaluate n₁ + n₁ = 80

  80 / (n₁ / n₀ + n₁ / n₂)

• Evaluate n₁ / n₀ = 2.6666666666667

  80 / (2.6666666666667 + n₁ / n₂)

• Evaluate n₁ / n₂ = 1.3333333333333

  80 / (2.6666666666667 + 1.3333333333333)

• Evaluate 2.6666666666667 + 1.3333333333333 = 4

  80 / 4

• Evaluate 80 / 4 = 20

  20
• The answer to the problem and the result of (n₁ + n₁) / (n₁ / n₀ + n₁ / n₂) is 20
