Luke and Harry shared some beads. Luke took
511 of the beads. After Luke lost 20 beads, Harry had twice as many beads as Luke. How many beads did Harry have in the end?
|
Luke |
Harry |
Before |
5 u |
6 u |
Change |
- 20 |
|
After |
1x3 = 3 u |
2x3 = 6 u |
The number of beads that Harry had remains the same. Make the number of beads that Harry had the same. LCM of 6 and 2 is 6.
Number of beads that Luke lost
= 5 u - 3 u
= 2 u
2 u = 20
1 u = 20 ÷ 2 = 10
Number of beads that Harry had in the end
= 6 u
= 6 x 10
= 60
Answer(s): 60
