A cm long wire is to be cut into two pieces so that one piece will be / th of the other, how many centimeters will the shorter piece be?

Calculated Answer

14

Step by Step Solution

In order to solve problem, you must evaluate n₀ - n₀ / (n₁ / n₂ + 1).

n₀ =	49
n₁ =	2
n₂ =	5

n₀ - n₀ / (n₁ / n₂ + 1)
Evaluate n₁ / n₂ = 0.4
n₀ - n₀ / (0.4 + 1)
Evaluate 0.4 + 1 = 1.4
n₀ - n₀ / 1.4
Evaluate n₀ / 1.4 = 35
n₀ - 35
Evaluate n₀ - 35 = 14
14
The answer to the problem and the result of n₀ - n₀ / (n₁ / n₂ + 1) is 14
