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