There were some stickers in Box T and Box U. After Owen transferred
25 of the stickers from Box T to Box U, the ratio of the number of stickers in Box T to that in Box U changed to 1 : 8. Find the ratio of the numbers of stickers in Box U to the number of stickers in Box T at first.

Box T |
Box U |
| Before |
5x1 =
5 u |
22 u |
| Change |
- 2x1 =
- 2 u |
+ 2 u |
| After |
3x1 =
3 u |
|
Comparing Box T and
Box U in the end |
1x3 =
3 u |
8x3 =
24 u |
The number of stickers in Box T in the end is repeated. Make the number of stickers in Box T in the end the same. LCM of 3 and 1 is 3.
At first
Box U : Box T
22: 5
Answer(s): 22: 5
