Do you know how to convert that into a fraction?

Sure, here's another way of doing it. 

(4+3i)(a+bi) = 4-3i

4a-3b + 3ai + 4bi = 4 - 3i

4a-3b = 4

3ai + 4bi = -3i

3a + 4b = -3

4a - 3b = 4

a = 7/25

b = -24/25

7/25 - 24/25i

The answer wasn't what cat said? I've been trying to use latex to write my answers down but I can't figure it out.

Oops, I def should've added some work.

I'll add my work below since I used a different method. 

Melody and I have the same answer, it's just in a different form. :))

Our answers are the same.  catmg just wrote it in decimal form.

You're welcome. :))

Glad you understand. 

Remember that conjugate is just the negative of the imaginary part, so a + bi turns into a - bi.

Gotcha! Thanks!

If you want more explantion, always ask for it.

I mean you can say, "Thanks for the answer but can you show me how you got that please"

I like it when people ask me questions related to my answer. 

It means I actually have an audience and someone at the other end is actually trying to learn from me.

Thanks Chris,
