Lucy has 2 times as many coins as Shiyun. Shiyun has
35 as many coins as Jen. If the three of them have a total of 168 coins, how many coins does Jen have?
Lucy |
Shiyun |
Jen |
2x3 |
1x3 |
|
|
3x1 |
5x1 |
6 u |
3 u |
5 u |
The number of coins that Shiyun has is repeated. Make the number of coins that Shiyun has the same. LCM of 1 and 3 is 3.
Total number of coins that the three of them have
= 6 u + 3 u + 5 u
= 14 u
14 u = 168
1 u = 168 ÷ 14 = 12
Number of coins that Jen has
= 5 u
= 5 x 12
= 60
Answer(s): 60
