Calculated Answer

8

Step by Step Solution

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

n₀ =	4000
n₁ =	640
n₂ =	2

(n₁ * 100) / (n₀ * n₂)
Evaluate n₁ * 100 = 64000
64000 / (n₀ * n₂)
Evaluate n₀ * n₂ = 8000
64000 / 8000
Evaluate 64000 / 8000 = 8
8
The answer to the problem and the result of (n₁ * 100) / (n₀ * n₂) is 8
