Last Monday, Valen had twice as many marbles as Flynn. Today, Valen gives 60 of his marbles to his friend. Now, Flynn has thrice as many marbles as Valen. How many marbles does Flynn have?
| |
Valen |
Flynn |
| Before |
2x3 =
6 u |
1x3 =
3 u |
| Change |
- 60 |
|
| After |
1 u |
3 u |
The number of marbles that Flynn had at first and in the end remains unchanged. Make the number of marbles that Flynn has the same. LCM of 1 and 3 is 3.
Number of marbles that Valen gives to his friend
= 6 u - 1 u
= 5 u
5 u = 60
1 u = 60 ÷ 5 = 12
Number of marbles that Flynn has
= 3 u
= 3 x 12
= 36
Answer(s): 36
