Lynn has 5 times as many wafers as Shiyun. The total number of Lynn's and Shiyun's wafers is 2 times of Roshel's. Lynn and Shiyun have 12 wafers more than Roshel's. How many less wafers does Roshel have than Lynn?
| Lynn |
Shiyun |
Roshel |
| 5x1 |
1x1 |
|
| 2x3 |
1x3 |
| 5 u |
1 u |
3 u |
The total number of wafers that Lynn and Shiyun have is repeated. Make the total number of wafers that Lynn and Shiyun have the same. LCM of 6 and 2 is 6.
Total number of wafers that Lynn and Shiyun have
= 5 u + 1 u
= 6 u
Number of more wafers that Lynn and Shiyun have than Roshel
= 6 u - 3 u
= 3 u
3 u = 12
1 u = 12 ÷ 3 = 4
Number of less wafers that Roshel has than Lynn
= 5 u - 3 u
= 2 u
= 2 x 4
= 8
Answer(s): 8
