Jaslyn has 4 times as many coins as Roshel. Roshel has
27 as many coins as Erika. If the three of them have a total of 170 coins, how many coins does Jaslyn have?
| Jaslyn |
Roshel |
Erika |
| 4x2 |
1x2 |
|
| |
2x1 |
7x1 |
| 8 u |
2 u |
7 u |
The number of coins that Roshel has is repeated. Make the number of coins that Roshel has the same. LCM of 1 and 2 is 2.
Total number of coins that the three of them have
= 8 u + 2 u + 7 u
= 17 u
17 u = 170
1 u = 170 ÷ 17 = 10
Number of coins that Jaslyn has
= 8 u
= 8 x 10
= 80
Answer(s): 80
