I dont know how to write this mathematically but i'll try- 64 is 66 2/3 of 96 set up the proportion 64 over x = 66 2/3 over 100 cross multiply and youll have 6400 and 66 2/3 x to find x, divide 6400 by 66 2/3 (aka 200/3) you should get 96 hope i helped (the answer can't be less than 64 since 64 is only part of the whole number)
