35The number of pens that Nora had at first is repeated. Make the number of pens that Nora had at first the same. LCM of 5 and 8 is 40.
Number of pens that Winnie had in the end
= 24 u + 25 u
= 49 u
Number of less pens that Nora had than Winnie in the end
= 49 u - 15 u
= 34 u
Number of less pens that Nora had than Winnie in the end in percent
=
3449 x 100%
≈ 69.4%
Answer(s): 69.4%
