Respuesta :
I think you would go like this: If 15 covers 5 inches then I know I am going to need at least 30 but I have 3 more spaces so I have to divide 5/15 (That is 15 divided by 5) The answer is 3 so I have to go 3 x 3 which is 9 and then I add
9 to 30 which is 39 so there is my answer. If I did it incorrect please tell me. :). I hope it helps.

Answer:
Total of 39 beads are required to fill this necklace of 13 inch length.
Step-by-step explanation:
Maggie is making a necklace using 13 inch string and identical beads.
Length of necklace = 13 inch
The 15 beads fill 5 inches of the string
Total beads used for filling 5 inches = 15
[tex]\texttt{Number of beads required to fill 1 inch = }\frac{15}{5}=3[/tex]
Number of beads required to fill 13 inch string = 13 x 3 = 39
Total of 39 beads are required to fill this necklace of 13 inch length.
