There are 80 stickers in Container G and 65 stickers in Container H.
Some stickers are transferred from Container G to Container H.
Container H has 55 more stickers than Container G.
How many stickers are transferred from Container G to Container H?

	Container G	Container H
Before	80	65
Change	- ?	+ ?
After	1 u	1 u + 55

Total number of stickers
= 80 + 65
= 145

In the end
Total number of stickers = 1 u + 1 u + 55 = 2 u + 55

The total number of stickers at first and in the end remains unchanged.

2 u + 55 = 145
2 u = 145 - 55 = 90

1 u = 90 ÷ 2 = 45

Number of stickers that are transferred from Container G to Container H
= Number of stickers in Container G at first - Number of stickers in Container G in the end
= 80 - 45
= 35

Answer(s): 35
