Call the size of the second fish x.
The first fish is twice as big so it is 2x.
The third fish is half the size of the first fish so it is 1/2 of 2x or just x.
The weight of the three fish added together is 2x+x+x=4x which is 64 ounces.
so 4x=64
x=64/4=16
So the first fish had a weight of 32 ounces and the other two fish each weighed 16 ounces.
