35The number of stickers that Tina had at first is repeated. Make the number of stickers that Tina had at first the same. LCM of 5 and 7 is 35.
Number of stickers that Kylie had in the end
= 21 u + 10 u
= 31 u
Number of less stickers that Tina had than Kylie in the end
= 31 u - 25 u
= 6 u
Number of less stickers that Tina had than Kylie in the end in percent
=
631 x 100%
≈ 19.4%
Answer(s): 19.4%
