310The number of cards that Lynn had at first is repeated. Make the number of cards that Lynn had at first the same. LCM of 10 and 8 is 40.
Number of cards that Nora had in the end
= 12 u + 25 u
= 37 u
Number of less cards that Lynn had than Nora in the end
= 37 u - 15 u
= 22 u
Number of less cards that Lynn had than Nora in the end in percent
=
2237 x 100%
≈ 59.5%
Answer(s): 59.5%
