Step by step solution

Step 1. Given information

$\begin{array}{l} Thegivenequationis \frac{2}{5} n = 14. \\ Wehavetosolvethegivenequation. \end{array}$

Step 2. Solving the equation

$\begin{array}{l} Now, \\ \Rightarrow \frac{2}{5} n = 14 \\ \Rightarrow 5 \times \frac{2}{5} n = 5 \times 14 [∵ Multiplybothsidesby5] \\ \Rightarrow 2 n = 70 \\ \Rightarrow \frac{2 n}{2} = \frac{70}{2} [∵ Dividebothsidesby2] \\ \Rightarrow n = 35 \end{array}$
