Emily has 2 times as many cards as Cindy. Cindy has
34 as many cards as Jade. If the three of them have a total of 104 cards, how many cards does Jade have?
| Emily |
Cindy |
Jade |
| 2x3 |
1x3 |
|
| |
3x1 |
4x1 |
| 6 u |
3 u |
4 u |
The number of cards that Cindy has is repeated. Make the number of cards that Cindy has the same. LCM of 1 and 3 is 3.
Total number of cards that the three of them have
= 6 u + 3 u + 4 u
= 13 u
13 u = 104
1 u = 104 ÷ 13 = 8
Number of cards that Jade has
= 4 u
= 4 x 8
= 32
Answer(s): 32
