Winnie has 3 times as many stickers as Linda. Linda has
23 as many stickers as Esther. If the three of them have a total of 55 stickers, how many stickers does Esther have?
| Winnie |
Linda |
Esther |
| 3x2 |
1x2 |
|
| |
2x1 |
3x1 |
| 6 u |
2 u |
3 u |
The number of stickers that Linda has is repeated. Make the number of stickers that Linda has the same. LCM of 1 and 2 is 2.
Total number of stickers that the three of them have
= 6 u + 2 u + 3 u
= 11 u
11 u = 55
1 u = 55 ÷ 11 = 5
Number of stickers that Esther has
= 3 u
= 3 x 5
= 15
Answer(s): 15
