There were some stickers in Box B and Box C. After Will transferred
23 of the stickers from Box B to Box C, the ratio of the number of stickers in Box B to that in Box C changed to 2 : 5. Find the ratio of the numbers of stickers in Box C to the number of stickers in Box B at first.

6 u |
1 u |
| Change |
- 2x2 =
- 4 u |
+ 4 u |
| After |
1x2 =
2 u |

Comparing Box B and
Box C in the end |
2x1 =
2 u |
5x1 =
5 u |
The number of stickers in Box B in the end is repeated. Make the number of stickers in Box B in the end the same. LCM of 1 and 2 is 2.
At first
