45The number of stamps that Emma had at first is repeated. Make the number of stamps that Emma had at first the same. LCM of 5 and 7 is 35.
Number of stamps that Julie had in the end
= 28 u + 15 u
= 43 u
Number of less stamps that Emma had than Julie in the end
= 43 u - 20 u
= 23 u
Number of less stamps that Emma had than Julie in the end in percent
=
2343 x 100%
≈ 53.5%
Answer(s): 53.5%
