35The number of pens that Lynn had at first is repeated. Make the number of pens that Lynn had at first the same. LCM of 5 and 7 is 35.
Number of pens that Cindy had in the end
= 21 u + 15 u
= 36 u
Number of less pens that Lynn had than Cindy in the end
= 36 u - 20 u
= 16 u
Number of less pens that Lynn had than Cindy in the end in percent
=
1636 x 100%
≈ 44.4%
Answer(s): 44.4%
