5 inches divided by 3 is 1.67 + .25 for the seam allowance + 1.92. So your strips for your 9 patch would be cut just shy of 2 inches. Not sure how many 8th's of an inch this would be.
1/8 is .125, 2/8 or 1/4 is .25, 3/8 is .375, 4/8 is a 1/2 of course, 5/8 is .625, 6/8 is 3/4, 7/8 is .875
the .92 would be closer to 15/16 which you can find on a ruler.
