Gwen has 3 times as many coins as Elyse. Elyse has
23 as many coins as Emily. If the three of them have a total of 88 coins, how many coins does Emily have?
Gwen |
Elyse |
Emily |
3x2 |
1x2 |
|
|
2x1 |
3x1 |
6 u |
2 u |
3 u |
The number of coins that Elyse has is repeated. Make the number of coins that Elyse has the same. LCM of 1 and 2 is 2.
Total number of coins that the three of them have
= 6 u + 2 u + 3 u
= 11 u
11 u = 88
1 u = 88 ÷ 11 = 8
Number of coins that Emily has
= 3 u
= 3 x 8
= 24
Answer(s): 24
