58 of what she had. How many more percent did Kathy have than Lynn in the end? Correct the answer to 1 decimal place.

Lynn |
Kathy |
Comparing Lynn and Kathy at first |
10x4 = 40 u |
1x4 = 4 u |
Before |
8x5 = 40 u |
|
Change |
- 5x5 = - 25 u |
+ 5x5 = + 25 u |
After |
3x5 = 15 u |
29 u |
10% =
10100 =
110The number of cards that Lynn had at first is repeated. Make the number of cards that Lynn had at first the same. LCM of 10 and 8 is 40.
Number of cards that Kathy had in the end
= 4 u + 25 u
= 29 u
Number of more cards that Kathy had than Lynn in the end
= 29 u - 15 u
= 14 u
Number of more cards that Kathy had than Lynn in the end in percent
=
1415 x 100%
≈ 93.3%
Answer(s): 93.3%
