There were some beads in Bag W and Bag X. After Albert transferred
23 of the beads from Bag W to Bag X, the ratio of the number of beads in Bag W to that in Bag X changed to 3 : 8. Find the ratio of the numbers of beads in Bag X to the number of beads in Bag W at first.
|
Bag W |
Bag X |
Before |
3x3 = 9 u |
2 u |
Change |
- 2x3 = - 6 u |
+ 6 u |
After |
1x3 = 3 u |
|
Comparing Bag W and Bag X in the end |
3x1 = 3 u |
8x1 = 8 u |
The number of beads in Bag W in the end is repeated. Make the number of beads in Bag W in the end the same. LCM of 1 and 3 is 3.
At first
Bag X : Bag W
2: 9
Answer(s): 2: 9
