Three girls used the same number of beads to make bracelets. Victoria used
35 of her beads, Rachel used
25 of hers and Tiffany used
23 of hers. They had a total of 272 beads at first. How many beads did each girl use?
Make the numerators the same.
LCM of 3, 2 and 2 = 6
35 Victoria's beads =
25 Rachel's beads =
23 Tiffany's beads
3x25x2 Victoria's beads =
2x35x3 Rachel's beads =
2x33x3 Tiffany's beads
610 Victoria's beads =
615 Rachel's beads =
69 Tiffany's beads

Total number of beads at first
= 10 u + 15 u + 9 u
= 34 u
34 u = 272
1 u = 272 ÷ 34 = 8
Number of beads that each girl used
= 6 u
= 6 x 8
= 48
Answer(s): 48
