Step by Step Solution

In order to solve problem, you must evaluate n₂ / (n₁ / n₀ - 1).

• n₂ / (n₁ / n₀ - 1)

• Evaluate n₁ / n₀ = 1.25

  n₂ / (1.25 - 1)

• Evaluate 1.25 - 1 = 0.25

  n₂ / 0.25

• Evaluate n₂ / 0.25 = 36

  36
• The answer to the problem and the result of n₂ / (n₁ / n₀ - 1) is 36
