Lynn has 4 times as many buttons as Opal. Opal has
27 as many buttons as Jen. If the three of them have a total of 119 buttons, how many buttons does Lynn have?
Lynn |
Opal |
Jen |
4x2 |
1x2 |
|
|
2x1 |
7x1 |
8 u |
2 u |
7 u |
The number of buttons that Opal has is repeated. Make the number of buttons that Opal has the same. LCM of 1 and 2 is 2.
Total number of buttons that the three of them have
= 8 u + 2 u + 7 u
= 17 u
17 u = 119
1 u = 119 ÷ 17 = 7
Number of buttons that Lynn has
= 8 u
= 8 x 7
= 56
Answer(s): 56
