Rachel has 3 times as many marbles as Gwen. Gwen has
38 as many marbles as Jane. If the three of them have a total of 160 marbles, how many marbles does Jane have?
| Rachel |
Gwen |
Jane |
| 3x3 |
1x3 |
|
| |
3x1 |
8x1 |
| 9 u |
3 u |
8 u |
The number of marbles that Gwen has is repeated. Make the number of marbles that Gwen has the same. LCM of 1 and 3 is 3.
Total number of marbles that the three of them have
= 9 u + 3 u + 8 u
= 20 u
20 u = 160
1 u = 160 ÷ 20 = 8
Number of marbles that Jane has
= 8 u
= 8 x 8
= 64
Answer(s): 64
