Dana has 4 times as many buttons as Penelope. Penelope has
34 as many buttons as Kylie. If the three of them have a total of 76 buttons, how many buttons does Dana have?
Dana |
Penelope |
Kylie |
4x3 |
1x3 |
|
|
3x1 |
4x1 |
12 u |
3 u |
4 u |
The number of buttons that Penelope has is repeated. Make the number of buttons that Penelope has the same. LCM of 1 and 3 is 3.
Total number of buttons that the three of them have
= 12 u + 3 u + 4 u
= 19 u
19 u = 76
1 u = 76 ÷ 19 = 4
Number of buttons that Dana has
= 12 u
= 12 x 4
= 48
Answer(s): 48
