Decreasing in pattern

I am trying to decrease 1 stitch on each RS row on a pattern that reads:

Row 1 K3 P2 K3 repeat to end

Row 2 P3 K2 P3 repeat to end

Do I do the decrease in the first 3 K stitches, or in the pattern repeat? Also, if in pattern repeat, do I P2 K2T K1 or P2 K2T K2? I’m pretty confused!

Does it say where to decrese?

I am trying to decrease 1 stitch on each RS row on a pattern that reads:

Row 1 K3 P2 K3 repeat to end

Row 2 P3 K2 P3 repeat to end

Ok, if row 1 is the rs, what I would do is k2t, k1, p2k3
row two when you get to the end you’ll end on a P2 since you decreased the row before
row 3, k2t *p2 k3)
row 4, end on a p1

basically all you want to do is the decreases on the rs row and then stay in the rib pattern as much as possible. Depending on how many decreases are called for, you might have to k2t on a k and a p or p2t with a p and a k.
