Answer:
0
Step-by-step explanation:
An integer is colloquially defined as a number that can be written without a fractional component.
-3/4 ---- It is a fraction itself, so it is a fractional component
0 ---- Has no fractional component
2.3 Pi ---- Pi is irrational and is a decimal, so is 2.3. Most of this is a fractional component already.
The only one we can't eliminate using just the definition is 0.
