Last Monday, Pierre had twice as many stickers as Paul. Today, Pierre gives 36 of his stickers to his cousin. Now, Paul has twice as many stickers as Pierre. How many stickers does Paul have?
| |
Pierre |
Paul |
| Before |
2x2 =
4 u |
1x2 =
2 u |
| Change |
- 36 |
|
| After |
1 u |
2 u |
The number of stickers that Paul had at first and in the end remains unchanged. Make the number of stickers that Paul has the same. LCM of 1 and 2 is 2.
Number of stickers that Pierre gives to his cousin
= 4 u - 1 u
= 3 u
3 u = 36
1 u = 36 ÷ 3 = 12
Number of stickers that Paul has
= 2 u
= 2 x 12
= 24
Answer(s): 24
