Three girls used the same number of seashells to make bracelets. Julie used
35 of her seashells, Zoe used
23 of hers and Xylia used
34 of hers. They had a total of 162 seashells at first. How many seashells did each girl use?
Make the numerators the same.
LCM of 3, 2 and 3 = 6
35 Julie's seashells =
23 Zoe's seashells =
34 Xylia's seashells
3x25x2 Julie's seashells =
2x33x3 Zoe's seashells =
3x24x2 Xylia's seashells
610 Julie's seashells =
69 Zoe's seashells =
68 Xylia's seashells

| Before |
10 u |
9 u |
8 u |
| Change |
- 6 u |
- 6 u |
- 6 u |
| After |
4 u |
3 u |
2 u |
Total number of seashells at first
= 10 u + 9 u + 8 u
= 27 u
27 u = 162
1 u = 162 ÷ 27 = 6
Number of seashells that each girl used
= 6 u
= 6 x 6
= 36
Answer(s): 36
