14The number of pens that Wendy had at first is repeated. Make the number of pens that Wendy had at first the same. LCM of 4 and 5 is 20.
Number of pens that Tina had in the end
= 5 u + 12 u
= 17 u
Number of less pens that Wendy had than Tina in the end
= 17 u - 8 u
= 9 u
Number of less pens that Wendy had than Tina in the end in percent
=
917 x 100%
≈ 52.9%
Answer(s): 52.9%
