There were some pencils in Packet M and Packet N. After Fabian transferred
34 of the pencils from Packet M to Packet N, the ratio of the number of pencils in Packet M to that in Packet N changed to 2 : 9. Find the ratio of the numbers of pencils in Packet M to the number of pencils in Packet N at first.
|
Packet M |
Packet N |
Before |
4x2 = 8 u |
3 u |
Change |
- 3x2 = - 6 u |
+ 6 u |
After |
1x2 = 2 u |
|
Comparing Packet M and Packet N in the end |
2x1 = 2 u |
9x1 = 9 u |
The number of pencils in Packet M in the end is repeated. Make the number of pencils in Packet M in the end the same. LCM of 1 and 2 is 2.
At first
Packet M : Packet N
8 : 3
Answer(s): 8 : 3
