Fanny has 2 times as many stickers as Shiyun. Shiyun has
57 as many stickers as Gillian. If the three of them have a total of 110 stickers, how many stickers does Gillian have?
| Fanny |
Shiyun |
Gillian |
| 2x5 |
1x5 |
|
| |
5x1 |
7x1 |
| 10 u |
5 u |
7 u |
The number of stickers that Shiyun has is repeated. Make the number of stickers that Shiyun has the same. LCM of 1 and 5 is 5.
Total number of stickers that the three of them have
= 10 u + 5 u + 7 u
= 22 u
22 u = 110
1 u = 110 ÷ 22 = 5
Number of stickers that Gillian has
= 7 u
= 7 x 5
= 35
Answer(s): 35
