25The number of buttons that Elyse had at first is repeated. Make the number of buttons that Elyse had at first the same. LCM of 5 and 8 is 40.
Number of buttons that Gillian had in the end
= 16 u + 35 u
= 51 u
Number of less buttons that Elyse had than Gillian in the end
= 51 u - 5 u
= 46 u
Number of less buttons that Elyse had than Gillian in the end in percent
=
4651 x 100%
≈ 90.2%
Answer(s): 90.2%
