Xuan has 4 times as many stickers as Shiyun. Shiyun has
56 as many stickers as Jean. If the three of them have a total of 217 stickers, how many stickers does Jean have?
Xuan |
Shiyun |
Jean |
4x5 |
1x5 |
|
|
5x1 |
6x1 |
20 u |
5 u |
6 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
= 20 u + 5 u + 6 u
= 31 u
31 u = 217
1 u = 217 ÷ 31 = 7
Number of stickers that Jean has
= 6 u
= 6 x 7
= 42
Answer(s): 42
