Fanny has 4 times as many pencils as Marion. Marion has
58 as many pencils as Zoe. If the three of them have a total of 231 pencils, how many pencils does Zoe have?
| Fanny |
Marion |
Zoe |
| 4x5 |
1x5 |
|
| |
5x1 |
8x1 |
| 20 u |
5 u |
8 u |
The number of pencils that Marion has is repeated. Make the number of pencils that Marion has the same. LCM of 1 and 5 is 5.
Total number of pencils that the three of them have
= 20 u + 5 u + 8 u
= 33 u
33 u = 231
1 u = 231 ÷ 33 = 7
Number of pencils that Zoe has
= 8 u
= 8 x 7
= 56
Answer(s): 56
