In order to solve problem, you must evaluate (100 - (n₁ * 100) / n₀) / ((n₁ * 100) / n₀) * 100.

n₀ =	50
n₁ =	15

(100 - (n₁ * 100) / n₀) / ((n₁ * 100) / n₀) * 100
Evaluate n₁ * 100 = 1500
(100 - 1500 / n₀) / ((n₁ * 100) / n₀) * 100
Evaluate 1500 / n₀ = 30
(100 - 30) / ((n₁ * 100) / n₀) * 100
Evaluate 100 - 30 = 70
70 / ((n₁ * 100) / n₀) * 100
Evaluate n₁ * 100 = 1500
70 / (1500 / n₀) * 100
Evaluate 1500 / n₀ = 30
70 / 30 * 100
Evaluate 70 / 30 = 2.3333333333333
2.3333333333333 * 100
Evaluate 2.3333333333333 * 100 = 233.33333333333
233.33333333333
The answer to the problem and the result of (100 - (n₁ * 100) / n₀) / ((n₁ * 100) / n₀) * 100 is 233.33333333333
