Wendy has 2 times as many cards as Emma. Emma has
67 as many cards as Elyse. If the three of them have a total of 200 cards, how many cards does Elyse have?

2x6 |
1x6 |

6x1 |
7x1 |
12 u |
6 u |
7 u |
The number of cards that Emma has is repeated. Make the number of cards that Emma has the same. LCM of 1 and 6 is 6.
Total number of cards that the three of them have
= 12 u + 6 u + 7 u
= 25 u
25 u = 200
1 u = 200 ÷ 25 = 8
Number of cards that Elyse has
= 7 u
= 7 x 8
= 56
Answer(s): 56
