Calculated Answer

22.5

Step by Step Solution

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

n₀ =	400
n₁ =	180
n₂ =	2

n₁ / (n₀ * n₂) * 100
Evaluate n₀ * n₂ = 800
n₁ / 800 * 100
Evaluate n₁ / 800 = 0.225
0.225 * 100
Evaluate 0.225 * 100 = 22.5
22.5
The answer to the problem and the result of n₁ / (n₀ * n₂) * 100 is 22.5
