Unit Rates Quick Check
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)
O 12 beads
15 beads
10 beads
13 beads
To find the unit rate, you divide the total number of beads by the number of friends. So, 156 beads ÷ 12 friends = 13 beads per bracelet.
Therefore, the unit rate of beads per bracelet is 13 beads.
To find the unit rate of beads per bracelet, we need to divide the total number of beads by the number of bracelets.
Total number of beads = 156
Number of friends = 12
Unit rate of beads per bracelet = Total number of beads / Number of bracelets
Unit rate of beads per bracelet = 156 / 12
Now, let's calculate the unit rate:
Unit rate of beads per bracelet = 13
Therefore, the correct answer is 13 beads. (Option D)
To find the unit rate of beads per bracelet, we need to divide the total number of beads (156) by the number of friends (12).
156 beads ÷ 12 friends = 13 beads per friend
Therefore, the unit rate of beads per bracelet is 13 beads.
