Kimberly has 4 times as many cards as Yoko. Yoko has
57 as many cards as Penelope. If the three of them have a total of 384 cards, how many cards does Kimberly have?
| Kimberly |
Yoko |
Penelope |
| 4x5 |
1x5 |
|
| |
5x1 |
7x1 |
| 20 u |
5 u |
7 u |
The number of cards that Yoko has is repeated. Make the number of cards that Yoko has the same. LCM of 1 and 5 is 5.
Total number of cards that the three of them have
= 20 u + 5 u + 7 u
= 32 u
32 u = 384
1 u = 384 ÷ 32 = 12
Number of cards that Kimberly has
= 20 u
= 20 x 12
= 240
Answer(s): 240
