Linda had 22 more erasers than Kimberly. After Kimberly gave away
14 of her erasers, Linda had twice as many erasers as Kimberly. How many erasers did Kimberly have at first?

Comparing Linda and
Kimberly at first |

| Before |
6 u |
4 u |
| Change |
|
- 1 u |
| After |
6 u |
3 u |
Comparing Linda and
Kimberly in the end |
2x3 =
6 u |
1x3 =
3 u |
Number of erasers that Kimberly had in the end is repeated. Make the number of erasers that Kimberly had in the end the same. LCM of 1 and 3 is 3.
Number of erasers that Linda had at first = 6 u
Number of erasers that Linda had more than Kimberly at first
= 6 u - 4 u
= 2 u
2 u = 22
1 u = 22 ÷ 2 = 11
Number of erasers that Kimberly had at first
= 4 u
= 4 x 11
= 44
Answer(s): 44
