Ruby is making friendship bracelets. She has a total of 156 beads to make bracelets for 12 friends. If she uses all the bees, what is the unit rate of beads per bracelet?

To find the unit rate of beads per bracelet, divide the total number of beads by the number of friends she is making bracelets for: 156 beads / 12 friends = <<156/12=13>>13 beads/friend. Answer: \boxed{13}.

To find the unit rate of beads per bracelet, divide the total number of beads by the number of friends:

156 beads ÷ 12 friends = 13 beads per friend

So, the unit rate of beads per bracelet is 13 beads.

To find the unit rate of beads per bracelet, you need to divide the total number of beads by the number of bracelets.

In this case, Ruby has 156 beads and she is making bracelets for 12 friends. So you divide 156 by 12:

156 ÷ 12 = 13

Therefore, the unit rate of beads per bracelet is 13 beads.
