Fanny has 4 times as many erasers as Xandra. Xandra has
35 as many erasers as Nicole. If the three of them have a total of 200 erasers, how many erasers does Nicole have?
| Fanny |
Xandra |
Nicole |
| 4x3 |
1x3 |
|
| |
3x1 |
5x1 |
| 12 u |
3 u |
5 u |
The number of erasers that Xandra has is repeated. Make the number of erasers that Xandra has the same. LCM of 1 and 3 is 3.
Total number of erasers that the three of them have
= 12 u + 3 u + 5 u
= 20 u
20 u = 200
1 u = 200 ÷ 20 = 10
Number of erasers that Nicole has
= 5 u
= 5 x 10
= 50
Answer(s): 50
