A fractions structure is that of:
count
size indicator of what you are counting
→
numerator
denominator
You can not directly add or subtract the counts (numerators) unless the size indicators (denominators) are the same.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Consider
3

Write as
3
+
2

Multiply by 1 and you do not change the value. However, 1 comes in many forms so you can change the way something looks without changing its true value

Putting it all together

But the size indicators are not the same. I chose to make them become 12

Now we may subtract the counts

Step-by-step explanation:
To find the domain, we find every single value that can exist along the x axis.
One can notice here that w is in the denominator, which means a value doesn't exist at 0, because we can't have 0 in the denominator.
Answer:
(-∞,0) U (0,∞)
