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?
The total number of beads per bracelet is the number of beads divided by the number of bracelets. So the unit rate of beads per bracelet is 156 beads / 12 bracelets = <<156/12=13>>13 beads/bracelet. Answer: \boxed{13}.
ustin starts going to a new fitness class. His smart watch tracks a total of 72 active minutes in the week. If he attended the class 3 times, what is the unit rate of active minutes per class?
To find the unit rate of beads per bracelet, we need to divide the total number of beads by the number of friends.
Total number of beads = 156
Number of friends = 12
Unit rate = Total number of beads / Number of friends
Unit rate = 156 / 12
Dividing 156 by 12, we get:
Unit rate = 13
Therefore, the unit rate of beads per bracelet is 13 beads.
To find the unit rate of beads per bracelet, you need to divide the total number of beads by the number of friends. In this case, Ruby has 156 beads for 12 friends.
To calculate the unit rate, divide the total number of beads by the number of friends:
156 beads / 12 friends = 13 beads per friend
Therefore, the unit rate of beads per bracelet is 13 beads per friend.
