Question

If $m=2$, find the value of $\frac{5m}{2}-4$.

Answer 1

Calculate the required value:

It is given that $m=2$.

And, the expression whose value is to be calculated is $\frac{5m}{2}-4$.

On substituting $m=2$ in $\frac{5m}{2}-4$, we get,

$\frac{5m}{2}-4=\frac{5\times 2}{2}-4$

$\Rightarrow \frac{5m}{2}-4=\frac{5\times 1}{1}-4$

$\Rightarrow \frac{5m}{2}-4=5-4$

$\Rightarrow \frac{5m}{2}-4=1$

Hence, the required value of $\frac{5m}{2}-4$ is $1$.
