Three girls used the same number of seashells to make bracelets. Sarah used
35 of her seashells, Cindy used
23 of hers and Pamela used
34 of hers. They had a total of 216 seashells at first. How many seashells did each girl use?
Make the numerators the same.
LCM of 3, 2 and 3 = 6
35 Sarah's seashells =
23 Cindy's seashells =
34 Pamela's seashells
3x25x2 Sarah's seashells =
2x33x3 Cindy's seashells =
3x24x2 Pamela's seashells
610 Sarah's seashells =
69 Cindy's seashells =
68 Pamela's seashells

3 u |
2 u |
Total number of seashells at first
= 10 u + 9 u + 8 u
= 27 u
27 u = 216
1 u = 216 ÷ 27 = 8
Number of seashells that each girl used
= 6 u
= 6 x 8
= 48
Answer(s): 48
