Hilda has 4 times as many marbles as Roshel. Roshel has
67 as many marbles as Sabrina. If the three of them have a total of 370 marbles, how many marbles does Sabrina have?
| Hilda |
Roshel |
Sabrina |
| 4x6 |
1x6 |
|
| |
6x1 |
7x1 |
| 24 u |
6 u |
7 u |
The number of marbles that Roshel has is repeated. Make the number of marbles that Roshel has the same. LCM of 1 and 6 is 6.
Total number of marbles that the three of them have
= 24 u + 6 u + 7 u
= 37 u
37 u = 370
1 u = 370 ÷ 37 = 10
Number of marbles that Sabrina has
= 7 u
= 7 x 10
= 70
Answer(s): 70
