There are 55 stickers in Container U and 20 stickers in Container V.
Some stickers are transferred from Container U to Container V.
Container U has 5 more stickers than Container V.
How many stickers are transferred from Container U to Container V?
|
Container U |
Container V |
Before |
55 |
20 |
Change |
- ? |
+ ? |
After |
1 u + 5 |
1 u |
Total number of stickers
= 55 + 20
= 75
Total number of stickers in the end = 1 u + 5 + 1 u = 2 u + 5
The total number of stickers at first and in the end remains unchanged.
2 u + 5 = 75
2 u = 75 - 5 = 70
1 u = 70 ÷ 2 = 35
Number of stickers that are transferred from Container U to Container V
= Number of stickers in Container V in the end - Number of stickers in Container V at first
= 35 - 20
= 15
Answer(s): 15
