Comparing Kimberly and Diana at first |
5x8 = 40 u |
3x8 = 24 u |
Before |
8x5 = 40 u |
|
Change |
- 3x5 = - 15 u |
+ 3x5 = + 15 u |
After |
5x5 = 25 u |
39 u |
60% =
60100 =
35The number of cards that Kimberly had at first is repeated. Make the number of cards that Kimberly had at first the same. LCM of 5 and 8 is 40.
Number of cards that Diana had in the end
= 24 u + 15 u
= 39 u
Number of less cards that Kimberly had than Diana in the end
= 39 u - 25 u
= 14 u
Number of less cards that Kimberly had than Diana in the end in percent
=
1439 x 100%
≈ 35.9%
Answer(s): 35.9%
