45The number of marbles that Hazel had at first is repeated. Make the number of marbles that Hazel had at first the same. LCM of 5 and 7 is 35.
Number of marbles that Kimberly had in the end
= 28 u + 20 u
= 48 u
Number of less marbles that Hazel had than Kimberly in the end
= 48 u - 15 u
= 33 u
Number of less marbles that Hazel had than Kimberly in the end in percent
=
3348 x 100%
≈ 68.8%
Answer(s): 68.8%
