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) Responses 13 beads 13 beads 10 beads 10 beads 12 beads 12 beads 15 beads

Answer 1

To calculate the unit rate of beads per bracelet, we need to divide the total number of beads by the number of friends (or bracelets Ruby is making).

Ruby has a total of 156 beads and is making bracelets for 12 friends.

\[ \text{Beads per bracelet} = \frac{\text{Total beads}}{\text{Number of friends}} = \frac{156}{12} \]

Calculating this:

\[ \frac{156}{12} = 13 \]

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