Step-by-step explanation:
First off, let's change everything to a common denominator. This will allow us to add the fractions!
To find a common denominator, we find a number that both 4, 28, and 1 can go into. 28 is the best choice, as 4 goes into it 7 times, 28 goes into it once, and 1 goes into it 28 times.
Let's change the first fraction into a number with a denominator of 28!
= 1. Multiplying a number by one doesn't change its value.
The second fraction, , already has a denominator of 28, so we don't have to do anything with it.
Now to the third number, -1:
Now, let's add them all up!
One last step, to simplify:
