Dana has 4 times as many buttons as Abi. Abi has
27 as many buttons as Hazel. If the three of them have a total of 153 buttons, how many buttons does Dana have?
Dana |
Abi |
Hazel |
4x2 |
1x2 |
|
|
2x1 |
7x1 |
8 u |
2 u |
7 u |
The number of buttons that Abi has is repeated. Make the number of buttons that Abi 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 = 153
1 u = 153 ÷ 17 = 9
Number of buttons that Dana has
= 8 u
= 8 x 9
= 72
Answer(s): 72
