Solve $\frac{x}{2}+ \frac{x}{4}=12$
Given: $\frac{x}{2}+ \frac{x}{4}=12$
To do: Find the value of $x$
Solution:
$\frac{x}{2}+ \frac{x}{4}=12$
Denominators are different , to make them same take LCM
LCM of 2 and 4 is 4
$\frac{x \times 2 }{ 2 \times 2} = \frac{2 x }{ 4}$
$\frac{x \times 1}{ 4 \times 1} = \frac{x }{ 4}$
$\frac{2 x }{ 4} + \frac{x }{ 4} = 12$
Denominators are same now, so we can add directly
$\frac{2 x + x }{ 4} = 12$
$\frac{3 x}{ 4} = 12$
$3 x = 12 \times 4$
$3 x = 48$
$ x = \frac{48 }{ 3}$ [$16 \times 3 = 48$]
$x = 16$
Therefore, the value of $x \ is \ 16$
