710The number of coins that Tiffany had at first is repeated. Make the number of coins that Tiffany had at first the same. LCM of 10 and 5 is 10.
Number of coins that Hazel had in the end
= 7 u + 4 u
= 11 u
Number of more coins that Hazel had than Tiffany in the end
= 11 u - 6 u
= 5 u
Number of more coins that Hazel had than Tiffany in the end in percent
=
56 x 100%
≈ 83.3%
Answer(s): 83.3%
