Rachel has 4 times as many pencils as Xylia. Xylia has
35 as many pencils as Roshel. If the three of them have a total of 40 pencils, how many pencils does Rachel have?
| Rachel |
Xylia |
Roshel |
| 4x3 |
1x3 |
|
| |
3x1 |
5x1 |
| 12 u |
3 u |
5 u |
The number of pencils that Xylia has is repeated. Make the number of pencils that Xylia has the same. LCM of 1 and 3 is 3.
Total number of pencils that the three of them have
= 12 u + 3 u + 5 u
= 20 u
20 u = 40
1 u = 40 ÷ 20 = 2
Number of pencils that Rachel has
= 12 u
= 12 x 2
= 24
Answer(s): 24
