If we have 156 beads and we can make one bracelet with 9 beads we divide 156 by 9 and get 17 1/3. since we cannot have 1/3 of a bracelet, we can make 17 bracelets.
You would divide 156 by 9 wich would give you 17.3 so you have to round it. When you round it you would get 17. So your answer would be 17. So you can make 17 bracelets with 156 beads.
