Jean and Anna shared some cards. Jean had 40% of what Anna had at first. Jean then gave Anna
47 of what she had. How many more percent did Anna have than Jean in the end? Correct the answer to 1 decimal place.

Jean |
Anna |
Comparing Jean and Anna at first |
5x7 = 35 u |
2x7 = 14 u |
Before |
7x5 = 35 u |
|
Change |
- 4x5 = - 20 u |
+ 4x5 = + 20 u |
After |
3x5 = 15 u |
34 u |
40% =
40100 =
25The number of cards that Jean had at first is repeated. Make the number of cards that Jean had at first the same. LCM of 5 and 7 is 35.
Number of cards that Anna had in the end
= 14 u + 20 u
= 34 u
Number of more cards that Anna had than Jean in the end
= 34 u - 15 u
= 19 u
Number of more cards that Anna had than Jean in the end in percent
=
1915 x 100%
≈ 126.7%
Answer(s): 126.7%
