So, what we will do is, multiply both top and bottom, by the
conjugate of the denominator, so, the denominator is 7 + 10i, so its conjugate is 7 - 10i then, let's do so.

It's easier then you'd expect it to be. There's no need to convert the fractions so that they all have a common denominator like you'd have to do when adding or subtracting fractions.
Let's take a look at something really simple.

We can multiply the numerators together so 1*2. We can multiply 4*6 to get the denominator.
This means that our fraction becomes
.
Now I'm assuming since you already know how to add fractions you'll know how to simply fractions. So 2/24 will become 1/12.
