Fanny has 4 times as many marbles as Diana. Diana has
35 as many marbles as Eva. If the three of them have a total of 180 marbles, how many marbles does Eva have?
| Fanny |
Diana |
Eva |
| 4x3 |
1x3 |
|
| |
3x1 |
5x1 |
| 12 u |
3 u |
5 u |
The number of marbles that Diana has is repeated. Make the number of marbles that Diana has the same. LCM of 1 and 3 is 3.
Total number of marbles that the three of them have
= 12 u + 3 u + 5 u
= 20 u
20 u = 180
1 u = 180 ÷ 20 = 9
Number of marbles that Eva has
= 5 u
= 5 x 9
= 45
Answer(s): 45
