310The number of stamps that Pamela had at first is repeated. Make the number of stamps that Pamela had at first the same. LCM of 10 and 7 is 70.
Number of stamps that Raeann had in the end
= 21 u + 50 u
= 71 u
Number of less stamps that Pamela had than Raeann in the end
= 71 u - 20 u
= 51 u
Number of less stamps that Pamela had than Raeann in the end in percent
=
5171 x 100%
≈ 71.8%
Answer(s): 71.8%
