310The number of coins that Hazel had at first is repeated. Make the number of coins that Hazel had at first the same. LCM of 10 and 5 is 10.
Number of coins that Vanessa had in the end
= 3 u + 4 u
= 7 u
Number of more coins that Vanessa had than Hazel in the end
= 7 u - 6 u
= 1 u
Number of more coins that Vanessa had than Hazel in the end in percent
=
16 x 100%
≈ 16.7%
Answer(s): 16.7%
