Add the following expression: 3 5 x,2 2 x,-4 5 x - Vidyadip

Question

Add the following expression:
$\frac{3}{5}\text{x},\frac{2}{2}\text{x},\frac{-4}{5}\text{x}$

✓

Answer

$\frac{3}{5}\text{x},\frac{2}{3}\text{x},\Big(\frac{-4}{5}\text{x}\Big)$
$=\frac{3}{5}\text{x}+\frac{2}{3}\text{x}+\frac{-4}{5}\text{x}$
$=\frac{9\text{x}+10\text{x}-12\text{x}}{15}$ (LCM of 5, 3 = 15)
$=\frac{19\text{x}-15\text{x}}{15}$
$=\frac{7}{15}\text{x}$
