710The number of erasers that Wendy had at first is repeated. Make the number of erasers that Wendy had at first the same. LCM of 10 and 7 is 70.
Number of erasers that Jade had in the end
= 49 u + 40 u
= 89 u
Number of less erasers that Wendy had than Jade in the end
= 89 u - 30 u
= 59 u
Number of less erasers that Wendy had than Jade in the end in percent
=
5989 x 100%
≈ 66.3%
Answer(s): 66.3%
