Ruby is making friendship bracelets. She has a total of 156 beads to make bracelets for 12 friends. If she uses all of the beads, what is the unit rate of beads per bracelet? (1 point)
To find the unit rate of beads per bracelet, we need to divide the total number of beads by the number of friends.
156 beads รท 12 friends = <<156/12=13>>13 beads per bracelet.
The unit rate of beads per bracelet is 13 beads. Answer: \boxed{13}.
