I find it much easier to understand with real numbers, so choose (almost) any numbers to replace m,n and p:
In a certain village,m 20 litres of water are required per household per month. At this rate, if there aren 10 households in the village, how long (in months) willp2000litres of water last?
Water required is 20*10=200 (m*n)
Water available is 2000 (p)
It will last 10 months (p/m*n)

Calculated Answer

Step by Step Solution

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

n₀ =	20
n₁ =	10
n₂ =	2000

n₂ / (n₀ * n₁)
Evaluate n₀ * n₁ = 200
n₂ / 200
Evaluate n₂ / 200 = 10
10
The answer to the problem and the result of n₂ / (n₀ * n₁) is 10
