There were some stickers in Bag F and Bag G. After Archie transferred
45 of the stickers from Bag F to Bag G, the ratio of the number of stickers in Bag F to that in Bag G changed to 2 : 9. Find the ratio of the numbers of stickers in Bag F to the number of stickers in Bag G at first.
|
Bag F |
Bag G |
Before |
5x2 = 10 u |
1 u |
Change |
- 4x2 = - 8 u |
+ 8 u |
After |
1x2 = 2 u |
|
Comparing Bag F and Bag G in the end |
2x1 = 2 u |
9x1 = 9 u |
The number of stickers in Bag F in the end is repeated. Make the number of stickers in Bag F in the end the same. LCM of 1 and 2 is 2.
At first
Bag F : Bag G
10 : 1
Answer(s): 10 : 1
