For inequalities when you divide/multiply/add/minus a number from one side do you have to do the same for the other side of the equation??

Question

except mutiply and divide by a negative number, you have to change the direction of the inequalities. I mean: if you have                             -x< 5
multiple both side by -1                                 (-1) *x < 5 *(-1)
the direction of inequality changes                         $$x\color{red}{>} -5$$

@Loser66 Nope that's not my question. What I meant is let's say you have a > b,
if you were to divide a by 3, do you have to do the same for the other side:

a/3>b/3?
