Elyse has 4 times as many buttons as Ivory. Ivory has
67 as many buttons as Dana. If the three of them have a total of 333 buttons, how many buttons does Elyse have?
Elyse |
Ivory |
Dana |
4x6 |
1x6 |
|
|
6x1 |
7x1 |
24 u |
6 u |
7 u |
The number of buttons that Ivory has is repeated. Make the number of buttons that Ivory has the same. LCM of 1 and 6 is 6.
Total number of buttons that the three of them have
= 24 u + 6 u + 7 u
= 37 u
37 u = 333
1 u = 333 ÷ 37 = 9
Number of buttons that Elyse has
= 24 u
= 24 x 9
= 216
Answer(s): 216
