710The number of beads that Olivia had at first is repeated. Make the number of beads that Olivia had at first the same. LCM of 10 and 5 is 10.
Number of beads that Emma had in the end
= 7 u + 6 u
= 13 u
Number of less beads that Olivia had than Emma in the end
= 13 u - 4 u
= 9 u
Number of less beads that Olivia had than Emma in the end in percent
=
913 x 100%
≈ 69.2%
Answer(s): 69.2%
