Question

Add the following expressions( 3/5)x, (2/5)x , (-4/5)x​

Answer 1

Answer:

We add the like terms:

=(3/5)x+(2/3)x+(−4/5)x

Now, L.C.M of 5,3,5=15

So,

=(9x+10x−12x)/15

=(7/15)x

Answer 2

$= \frac{3}{5} x + \frac{2}{5} x - \frac{4}{5} x$

$= \frac{3x + 2x - 4x}{5}$

$= \frac{5x - 4x}{5}$

$= \frac{x}{5}$
