Find $m$, if $m=\frac{4}{5}(m+12)$.

Given:

$m=\frac{4}{5}(m+12)$.

To do:

We have to find the value of $m$.

Solution:

$m=\frac{4}{5}(m+12)$

$\Rightarrow 5(m)=(4)(m+12)$        (On cross multiplication)

$\Rightarrow 5m=4m+4(12)$

$\Rightarrow 5m-4m=48$

$\Rightarrow m=48$

The value of $m$ is $48$.
