Xuan has 2 times as many pencils as Jean. Jean has
35 as many pencils as Wendy. If the three of them have a total of 126 pencils, how many pencils does Wendy have?
Xuan |
Jean |
Wendy |
2x3 |
1x3 |
|
|
3x1 |
5x1 |
6 u |
3 u |
5 u |
The number of pencils that Jean has is repeated. Make the number of pencils that Jean has the same. LCM of 1 and 3 is 3.
Total number of pencils that the three of them have
= 6 u + 3 u + 5 u
= 14 u
14 u = 126
1 u = 126 ÷ 14 = 9
Number of pencils that Wendy has
= 5 u
= 5 x 9
= 45
Answer(s): 45
