There were some marbles in Packet B and Packet C. After Zane transferred
35 of the marbles from Packet B to Packet C, the ratio of the number of marbles in Packet B to that in Packet C changed to 1 : 8. Find the ratio of the numbers of marbles in Packet B to the number of marbles in Packet C at first.
|
Packet B |
Packet C |
Before |
5x1 = 5 u |
13 u |
Change |
- 3x1 = - 3 u |
+ 3 u |
After |
2x1 = 2 u |
|
Comparing Packet B and Packet C in the end |
1x2 = 2 u |
8x2 = 16 u |
The number of marbles in Packet B in the end is repeated. Make the number of marbles in Packet B in the end the same. LCM of 2 and 1 is 2.
At first
Packet B : Packet C
5 : 13
Answer(s): 5 : 13
