Gabby has 4 times as many buttons as Rachel. Rachel has
27 as many buttons as Jane. If the three of them have a total of 34 buttons, how many buttons does Gabby have?
Gabby |
Rachel |
Jane |
4x2 |
1x2 |
|
|
2x1 |
7x1 |
8 u |
2 u |
7 u |
The number of buttons that Rachel has is repeated. Make the number of buttons that Rachel 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 = 34
1 u = 34 ÷ 17 = 2
Number of buttons that Gabby has
= 8 u
= 8 x 2
= 16
Answer(s): 16
