Oscar and Valen shared some coins. Oscar took
37 of the coins. After Oscar lost 18 coins, Valen had four times as many coins as Oscar. How many coins did Valen have in the end?
|
Oscar |
Valen |
Before |
3 u |
4 u |
Change |
- 18 |
|
After |
1x1 = 1 u |
4x1 = 4 u |
The number of coins that Valen had remains the same. Make the number of coins that Valen had the same. LCM of 4 and 4 is 4.
Number of coins that Oscar lost
= 3 u - 1 u
= 2 u
2 u = 18
1 u = 18 ÷ 2 = 9
Number of coins that Valen had in the end
= 4 u
= 4 x 9
= 36
Answer(s): 36
