Mary has 2 times as many buttons as Lynn. Lynn has
34 as many buttons as Pamela. If the three of them have a total of 156 buttons, how many buttons does Pamela have?
| Mary |
Lynn |
Pamela |
| 2x3 |
1x3 |
|
| |
3x1 |
4x1 |
| 6 u |
3 u |
4 u |
The number of buttons that Lynn has is repeated. Make the number of buttons that Lynn has the same. LCM of 1 and 3 is 3.
Total number of buttons that the three of them have
= 6 u + 3 u + 4 u
= 13 u
13 u = 156
1 u = 156 ÷ 13 = 12
Number of buttons that Pamela has
= 4 u
= 4 x 12
= 48
Answer(s): 48
