Billy and Valen shared some beads. Billy took
511 of the beads. After Billy lost 18 beads, Valen had thrice as many beads as Billy. How many beads did Valen have in the end?

Billy |
Valen |
Before |
5 u |
6 u |
Change |
- 18 |
|
After |
1x2 = 2 u |
3x2 = 6 u |
The number of beads that Valen had remains the same. Make the number of beads that Valen had the same. LCM of 6 and 3 is 6.
Number of beads that Billy lost
= 5 u - 2 u
= 3 u
3 u = 18
1 u = 18 ÷ 3 = 6
Number of beads that Valen had in the end
= 6 u
= 6 x 6
= 36
Answer(s): 36
