Three girls used the same number of seashells to make bracelets. Lynn used
25 of her seashells, Zara used
34 of hers and Winnie used
23 of hers. They had a total of 96 seashells at first. How many seashells did each girl use?
Make the numerators the same.
LCM of 2, 3 and 2 = 6
25 Lynn's seashells =
34 Zara's seashells =
23 Winnie's seashells
2x35x3 Lynn's seashells =
3x24x2 Zara's seashells =
2x33x3 Winnie's seashells
615 Lynn's seashells =
68 Zara's seashells =
69 Winnie's seashells

3 u |
Total number of seashells at first
= 15 u + 8 u + 9 u
= 32 u
32 u = 96
1 u = 96 ÷ 32 = 3
Number of seashells that each girl used
= 6 u
= 6 x 3
= 18
Answer(s): 18
