25The number of coins that Olivia had at first is repeated. Make the number of coins that Olivia had at first the same. LCM of 5 and 7 is 35.
Number of coins that Diana had in the end
= 14 u + 20 u
= 34 u
Number of less coins that Olivia had than Diana in the end
= 34 u - 15 u
= 19 u
Number of less coins that Olivia had than Diana in the end in percent
=
1934 x 100%
≈ 55.9%
Answer(s): 55.9%
