25The number of pens that Gillian had at first is repeated. Make the number of pens that Gillian had at first the same. LCM of 5 and 8 is 40.
Number of pens that Dana had in the end
= 16 u + 25 u
= 41 u
Number of less pens that Gillian had than Dana in the end
= 41 u - 15 u
= 26 u
Number of less pens that Gillian had than Dana in the end in percent
=
2641 x 100%
≈ 63.4%
Answer(s): 63.4%
