There were some stickers in Bag V and Bag W. After Carl transferred
15 of the stickers from Bag V to Bag W, the ratio of the number of stickers in Bag V to that in Bag W changed to 1 : 7. Find the ratio of the numbers of stickers in Bag V to the number of stickers in Bag W at first.
|
Bag V |
Bag W |
Before |
5x1 = 5 u |
27 u |
Change |
- 1x1 = - 1 u |
+ 1 u |
After |
4x1 = 4 u |
|
Comparing Bag V and Bag W in the end |
1x4 = 4 u |
7x4 = 28 u |
The number of stickers in Bag V in the end is repeated. Make the number of stickers in Bag V in the end the same. LCM of 4 and 1 is 4.
At first
Bag V : Bag W
5 : 27
Answer(s): 5 : 27
