Wendy has 3 times as many marbles as Tina. Tina has
35 as many marbles as Natalie. If the three of them have a total of 153 marbles, how many marbles does Natalie have?
| Wendy |
Tina |
Natalie |
| 3x3 |
1x3 |
|
| |
3x1 |
5x1 |
| 9 u |
3 u |
5 u |
The number of marbles that Tina has is repeated. Make the number of marbles that Tina has the same. LCM of 1 and 3 is 3.
Total number of marbles that the three of them have
= 9 u + 3 u + 5 u
= 17 u
17 u = 153
1 u = 153 ÷ 17 = 9
Number of marbles that Natalie has
= 5 u
= 5 x 9
= 45
Answer(s): 45
