Kylie has 3 times as many cards as Vanessa. Vanessa has
45 as many cards as Olivia. If the three of them have a total of 63 cards, how many cards does Kylie have?
| Kylie |
Vanessa |
Olivia |
| 3x4 |
1x4 |
|
| |
4x1 |
5x1 |
| 12 u |
4 u |
5 u |
The number of cards that Vanessa has is repeated. Make the number of cards that Vanessa has the same. LCM of 1 and 4 is 4.
Total number of cards that the three of them have
= 12 u + 4 u + 5 u
= 21 u
21 u = 63
1 u = 63 ÷ 21 = 3
Number of cards that Kylie has
= 12 u
= 12 x 3
= 36
Answer(s): 36
