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