Natalie has 4 times as many erasers as Kylie. Kylie has
56 as many erasers as Elyse. If the three of them have a total of 186 erasers, how many erasers does Natalie have?
Natalie |
Kylie |
Elyse |
4x5 |
1x5 |
|
|
5x1 |
6x1 |
20 u |
5 u |
6 u |
The number of erasers that Kylie has is repeated. Make the number of erasers that Kylie has the same. LCM of 1 and 5 is 5.
Total number of erasers that the three of them have
= 20 u + 5 u + 6 u
= 31 u
31 u = 186
1 u = 186 ÷ 31 = 6
Number of erasers that Natalie has
= 20 u
= 20 x 6
= 120
Answer(s): 120
