Jen has 4 times as many cards as Tiffany. Tiffany has
25 as many cards as Hazel. If the three of them have a total of 105 cards, how many cards does Hazel have?
| Jen |
Tiffany |
Hazel |
| 4x2 |
1x2 |
|
| |
2x1 |
5x1 |
| 8 u |
2 u |
5 u |
The number of cards that Tiffany has is repeated. Make the number of cards that Tiffany has the same. LCM of 1 and 2 is 2.
Total number of cards that the three of them have
= 8 u + 2 u + 5 u
= 15 u
15 u = 105
1 u = 105 ÷ 15 = 7
Number of cards that Hazel has
= 5 u
= 5 x 7
= 35
Answer(s): 35
