3 pounds
The fish weighs 3/4 of a fish plus 3/4 of a pound. Therefore, 3/4 of a pound is 1/4 of the weight of the fish. So the weight is 4 x 3/4 of a pound = 3 pounds

All the wonderful equations only work if every fish is the same weight!
So my answer is 3 and 3/4.
I work this out from Fish caught = 3/4 different fish + 3/4lbs.
For ease of maths my different fish is a 4lbs one I caught earlier so the equation is then
Fish caught = 3/4 of a 4lb fish + 3/4lbs
therefore Fish caught = 3lbs + 3/4lbs
Using this logic you can make the fish any weight you want by selecting the weight of the other fish.
The question needs to be worded more carefully.

so 1/4 of the fish is 3/4 of a pound.
so 4/4 of the fish is 3 pounds

We know the man caught a fish weighing:
3/4 of fish + 3/4 of pound
So, making the weight of the fish the x-variable, the following formula can be deduced:
3/4x + 3/4 (of a pound, which is one, and therefore makes no difference)= x
=> 3/4x + 0.75 = x
-0.25=-0.75
x = 3
Answer: the fish weights 3 pounds

This question only works if it is part of a logic class, because then the definition of "fish" would be known to be a thing weighing three pounds. Otherwise, there is not enough information.

The fish is 3 pounds.
How I got that:
Let us say that fish = the variable f.
So from what you said and assuming that f is also in the measurement of lbs.
f= 3/4f + 3/4lbs.
(subtract 3/4 f from both sides)
f - 3/4 f = 3/4 lbs.
1/4 f= 3/4 lbs.
(multiply both sides by 4)
f = 3lbs.
So the fish equals 3 pounds.

Why do we have to keep re-interpreting people's questions on here?
Can't you just say a quarter of the fish = 3/4 lb?

3 pounds
Let x be the weight of the fish and that its units is in pounds.
x = (3/4)x + 3/4
x - (3/4)x = 3/4
(1/4)x = 3/4
x = 3 pounds.

Get your fish
Cut it in four
Put one piece aside (that piece weighs three quarters of a pound)
You have three other pieces and each piece weighs three quarters of a pound.
So, three quarters+three quarters+three quarters+three quarters
That comes to twelve quarters.
If four quarters makes one pound.
Then twelve quarters makes three pounds.

He must have caught 3/4 of a fish
