Emily has 4 times as many cards as Kimberly. Kimberly has
67 as many cards as Olivia. If the three of them have a total of 333 cards, how many cards does Olivia have?
| Emily |
Kimberly |
Olivia |
| 4x6 |
1x6 |
|
| |
6x1 |
7x1 |
| 24 u |
6 u |
7 u |
The number of cards that Kimberly has is repeated. Make the number of cards that Kimberly has the same. LCM of 1 and 6 is 6.
Total number of cards that the three of them have
= 24 u + 6 u + 7 u
= 37 u
37 u = 333
1 u = 333 ÷ 37 = 9
Number of cards that Olivia has
= 7 u
= 7 x 9
= 63
Answer(s): 63
