Zara has 4 times as many buttons as Jaslyn. Jaslyn has
37 as many buttons as Jane. If the three of them have a total of 44 buttons, how many buttons does Jane have?
Zara |
Jaslyn |
Jane |
4x3 |
1x3 |
|
|
3x1 |
7x1 |
12 u |
3 u |
7 u |
The number of buttons that Jaslyn has is repeated. Make the number of buttons that Jaslyn has the same. LCM of 1 and 3 is 3.
Total number of buttons that the three of them have
= 12 u + 3 u + 7 u
= 22 u
22 u = 44
1 u = 44 ÷ 22 = 2
Number of buttons that Jane has
= 7 u
= 7 x 2
= 14
Answer(s): 14
