34The number of stamps that Eva had at first is repeated. Make the number of stamps that Eva had at first the same. LCM of 4 and 7 is 28.
Number of stamps that Kylie had in the end
= 21 u + 12 u
= 33 u
Number of less stamps that Eva had than Kylie in the end
= 33 u - 16 u
= 17 u
Number of less stamps that Eva had than Kylie in the end in percent
=
1733 x 100%
≈ 51.5%
Answer(s): 51.5%
