Xylia has 4 times as many pencils as Sabrina. Sabrina has
57 as many pencils as Min. If the three of them have a total of 352 pencils, how many pencils does Min have?
| Xylia |
Sabrina |
Min |
| 4x5 |
1x5 |
|
| |
5x1 |
7x1 |
| 20 u |
5 u |
7 u |
The number of pencils that Sabrina has is repeated. Make the number of pencils that Sabrina has the same. LCM of 1 and 5 is 5.
Total number of pencils that the three of them have
= 20 u + 5 u + 7 u
= 32 u
32 u = 352
1 u = 352 ÷ 32 = 11
Number of pencils that Min has
= 7 u
= 7 x 11
= 77
Answer(s): 77
