Hazel has 2 times as many erasers as Kimberly. Kimberly has
25 as many erasers as Cindy. If the three of them have a total of 66 erasers, how many erasers does Cindy have?
| Hazel |
Kimberly |
Cindy |
| 2x2 |
1x2 |
|
| |
2x1 |
5x1 |
| 4 u |
2 u |
5 u |
The number of erasers that Kimberly has is repeated. Make the number of erasers that Kimberly has the same. LCM of 1 and 2 is 2.
Total number of erasers that the three of them have
= 4 u + 2 u + 5 u
= 11 u
11 u = 66
1 u = 66 ÷ 11 = 6
Number of erasers that Cindy has
= 5 u
= 5 x 6
= 30
Answer(s): 30
