There were some beads in Packet W and Packet X. After Owen transferred
14 of the beads from Packet W to Packet X, the ratio of the number of beads in Packet W to that in Packet X changed to 1 : 8. Find the ratio of the numbers of beads in Packet X to the number of beads in Packet W at first.
|
Packet W |
Packet X |
Before |
4x1 = 4 u |
23 u |
Change |
- 1x1 = - 1 u |
+ 1 u |
After |
3x1 = 3 u |
|
Comparing Packet W and Packet X in the end |
1x3 = 3 u |
8x3 = 24 u |
The number of beads in Packet W in the end is repeated. Make the number of beads in Packet W in the end the same. LCM of 3 and 1 is 3.
At first
Packet X : Packet W
23: 4
Answer(s): 23: 4
