There were some coins in Packet W and Packet X. After Fabian transferred
23 of the coins from Packet W to Packet X, the ratio of the number of coins in Packet W to that in Packet X changed to 2 : 5. Find the ratio of the numbers of coins in Packet X to the number of coins in Packet W at first.
|
Packet W |
Packet X |
Before |
3x2 = 6 u |
1 u |
Change |
- 2x2 = - 4 u |
+ 4 u |
After |
1x2 = 2 u |
|
Comparing Packet W and Packet X in the end |
2x1 = 2 u |
5x1 = 5 u |
The number of coins in Packet W in the end is repeated. Make the number of coins in Packet W in the end the same. LCM of 1 and 2 is 2.
At first
Packet X : Packet W
1: 6
Answer(s): 1: 6
