Shiyun has 2 times as many cards as Vanessa. Vanessa has
56 as many cards as Anna. If the three of them have a total of 126 cards, how many cards does Shiyun have?
| Shiyun |
Vanessa |
Anna |
| 2x5 |
1x5 |
|
| |
5x1 |
6x1 |
| 10 u |
5 u |
6 u |
The number of cards that Vanessa has is repeated. Make the number of cards that Vanessa has the same. LCM of 1 and 5 is 5.
Total number of cards that the three of them have
= 10 u + 5 u + 6 u
= 21 u
21 u = 126
1 u = 126 ÷ 21 = 6
Number of cards that Shiyun has
= 10 u
= 10 x 6
= 60
Answer(s): 60
