Archie and Ian shared some stickers. Archie took
511 of the stickers. After Archie lost 10 stickers, Ian had twice as many stickers as Archie. How many stickers did Ian have in the end?
|
Archie |
Ian |
Before |
5 u |
6 u |
Change |
- 10 |
|
After |
1x3 = 3 u |
2x3 = 6 u |
The number of stickers that Ian had remains the same. Make the number of stickers that Ian had the same. LCM of 6 and 2 is 6.
Number of stickers that Archie lost
= 5 u - 3 u
= 2 u
2 u = 10
1 u = 10 ÷ 2 = 5
Number of stickers that Ian had in the end
= 6 u
= 6 x 5
= 30
Answer(s): 30
