+ 5x5 =
+ 25 u |
| After |
3x5 =

35The number of stamps that Esther had at first is repeated. Make the number of stamps that Esther had at first the same. LCM of 5 and 8 is 40.
Number of stamps that Erika had in the end
= 24 u + 25 u
= 49 u
Number of more stamps that Erika had than Esther in the end
= 49 u - 15 u
= 34 u
Number of more stamps that Erika had than Esther in the end in percent
=
3415 x 100%
≈ 226.7%
Answer(s): 226.7%
