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 average number of beads per bracelet?

Question

a) 13
b) 12
c) 14
d) 15

Answer 1

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

Ruby has 156 beads and 12 friends:

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

Now, performing the division:

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

Therefore, the average number of beads per bracelet is \( \boxed{13} \).
