So we start of with 64 pounds. Then, we subtract 1/4 of 64 (aka 64/4) because she keeps it for her family. Then, we subtract 1/8 of 64/4 (aka 64/4 then /8) because she gives 1/8 of the remainder to her club. Then, we take that number and divide it among 8 friends. So, let's put this into math.
64/4 = 16 pounds she gives to her family
64-16 = 48 pounds left
48/8 = 6 pounds she gives to her club
48 - 6 = 42 pounds left
42/8 = 5.25 pounds each of her friends get. That translates into 84 ounces
