$\displaystyle \frac{5ab}{12}-2cb$

or

$\displaystyle \frac{5ab}{12-2cb}$

Until you learn to use $\LaTeX$, I recommend you use bracketing symbols to make it clear exactly what the denominator is.

If the first choice above is what you intend, then you could type (5ab/12) - 2cb, and if the second choice is what you intend, then you could type (5ab)/(12 - 2cb).

Do you see how that removes the potential ambiguity?

I think you have made a great start...you have come to a wonderful forum to get help, and I think once you get the hang of the procedure for these, you will understand what you need to do for other similar problems....Can you recommend some books for me to learn these kinds of problems.

Books are good, but the feedback you get from helpers on a forum is much better.
