There were some stickers in Bag J and Bag K. After Ken transferred
23 of the stickers from Bag J to Bag K, the ratio of the number of stickers in Bag J to that in Bag K changed to 2 : 5. Find the ratio of the numbers of stickers in Bag K to the number of stickers in Bag J at first.
|
Bag J |
Bag K |
Before |
3x2 = 6 u |
1 u |
Change |
- 2x2 = - 4 u |
+ 4 u |
After |
1x2 = 2 u |
|
Comparing Bag J and Bag K in the end |
2x1 = 2 u |
5x1 = 5 u |
The number of stickers in Bag J in the end is repeated. Make the number of stickers in Bag J in the end the same. LCM of 1 and 2 is 2.
At first
Bag K : Bag J
1: 6
Answer(s): 1: 6
