Hilda has 4 times as many buttons as Nicole. Nicole has
35 as many buttons as Linda. If the three of them have a total of 220 buttons, how many buttons does Linda have?
Hilda |
Nicole |
Linda |
4x3 |
1x3 |
|
|
3x1 |
5x1 |
12 u |
3 u |
5 u |
The number of buttons that Nicole has is repeated. Make the number of buttons that Nicole has the same. LCM of 1 and 3 is 3.
Total number of buttons that the three of them have
= 12 u + 3 u + 5 u
= 20 u
20 u = 220
1 u = 220 ÷ 20 = 11
Number of buttons that Linda has
= 5 u
= 5 x 11
= 55
Answer(s): 55
