Zoe has 4 times as many buttons as Nicole. Nicole has
25 as many buttons as Ivory. If the three of them have a total of 75 buttons, how many buttons does Zoe have?
Zoe |
Nicole |
Ivory |
4x2 |
1x2 |
|
|
2x1 |
5x1 |
8 u |
2 u |
5 u |
The number of buttons that Nicole has is repeated. Make the number of buttons that Nicole has the same. LCM of 1 and 2 is 2.
Total number of buttons that the three of them have
= 8 u + 2 u + 5 u
= 15 u
15 u = 75
1 u = 75 ÷ 15 = 5
Number of buttons that Zoe has
= 8 u
= 8 x 5
= 40
Answer(s): 40
