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