There were some stickers in Bag F and Bag G. After Neave transferred
25 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 : 5. 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 |
11 u |
Change |
- 2x2 = - 4 u |
+ 4 u |
After |
3x2 = 6 u |
|
Comparing Bag F and Bag G in the end |
2x3 = 6 u |
5x3 = 15 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 3 and 2 is 6.
At first
Bag F : Bag G
10 : 11
Answer(s): 10 : 11
