help with multiples please

[gcgrammy]

I have a pattern that says: cast on 182 sts on a circular needle. Then it says to do 6 rows of 2 different rows. Then the body of the pattern consists of 10 rows, each row beginning and ending with a border of 6 K sts. My question is: how do I figure out the multiple to change the width, as there is only 1 row with any ( ). In other words, I was told to multiply the stitches in the ( ) but there really aren't any! By the way, the pattern is Bernat Softee Chunky Twists Blanket to Knit. If anyone can help me make this blanket not as wide, I would appreciate it! Thanks so much!

Looks like it may be this pattern. Look at the sts between the *s, that is also another way of showing repeated stitches, more commonly used than (). Looks like it's a multiple of 10 sts, so decrease the CO number by 10, 20, etc.
