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