Natalie has 4 times as many cards as Zara. Zara has
23 as many cards as Esther. If the three of them have a total of 91 cards, how many cards does Natalie have?
| Natalie |
Zara |
Esther |
| 4x2 |
1x2 |
|
| |
2x1 |
3x1 |
| 8 u |
2 u |
3 u |
The number of cards that Zara has is repeated. Make the number of cards that Zara has the same. LCM of 1 and 2 is 2.
Total number of cards that the three of them have
= 8 u + 2 u + 3 u
= 13 u
13 u = 91
1 u = 91 ÷ 13 = 7
Number of cards that Natalie has
= 8 u
= 8 x 7
= 56
Answer(s): 56
