Rachel has 2 times as many marbles as Gillian. Gillian has
35 as many marbles as Elyse. If the three of them have a total of 98 marbles, how many marbles does Elyse have?
| Rachel |
Gillian |
Elyse |
| 2x3 |
1x3 |
|
| |
3x1 |
5x1 |
| 6 u |
3 u |
5 u |
The number of marbles that Gillian has is repeated. Make the number of marbles that Gillian has the same. LCM of 1 and 3 is 3.
Total number of marbles that the three of them have
= 6 u + 3 u + 5 u
= 14 u
14 u = 98
1 u = 98 ÷ 14 = 7
Number of marbles that Elyse has
= 5 u
= 5 x 7
= 35
Answer(s): 35
