Answer 1

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

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

\[ \text{Unit rate} = \frac{\text{Total beads}}{\text{Number of friends}} = \frac{156}{12} \]

Now we perform the division:

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

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

The correct response is:

13 beads
