Calculated Answer

0.5

Step by Step Solution

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

n₀ =	10
n₁ =	1
n₂ =	5

(n₀ / 100) / (n₁ / n₂)
Evaluate n₀ / 100 = 0.1
0.1 / (n₁ / n₂)
Evaluate n₁ / n₂ = 0.2
0.1 / 0.2
Evaluate 0.1 / 0.2 = 0.5
0.5
The answer to the problem and the result of (n₀ / 100) / (n₁ / n₂) is 0.5
