You can not add (or subtract) numbers, or in this case fractions, with variables unless both numbers contain the same variable.
Here is an example:
You can not add
1/2 + x
because the fraction does not contain the variable 'x'
This equation however is possible to solve:
1/2x + x
because both numbers contain the variable 'x'
But don't get tricked
It is impossible to add or subtract numbers with different variables, as each variable has a different value
Example:
1/2x + 1/2y
They are known as ratios.
They are ratios.
It is a ratio.
It depends on whether you are working with variables. You cannot add terms with variables that have unlike exponents.
well, if you want to add apples to bananas you can't do that it's the same with variables, the coefficients can be different but to add and subtract the variables have to be the same for ex: you can't do 4x+3y because they have different variables you can do 4x+3x because they have the same variables all you do is add the coefficients and keep the variable so you would get 7x
There can be variables in fractions, such as in 2*x/3
There is no such fraction since there is not a linear relationship between the two variables.

You add them.
you add all the numbers together then divide the answer by the number of numbers there are
