Find the common denominator.

$\frac{12\cdot 15}{15}-\frac{6}{15}+\frac{6\cdot 5\cdot 15}{15}+\frac{-9\cdot 15}{15}$

Combine the numerators over the common denominator.

$\frac{12\cdot 15-6+6\cdot 5\cdot 15-9\cdot 15}{15}$

Simplify each term.

$\frac{180-6+450-135}{15}$

Reduce the expression by cancelling the common factors.

$\frac{163}{5}$

The result can be shown in multiple forms.

Exact Form:

$\frac{163}{5}$

Set up the form for the partial fraction decomposition. Do not solve for A, B, C, and so on.

$\frac{x-14}{{x}^{2}-3x}$

How do you solve this fraction?

$\frac{2}{3}-\frac{1}{16}$

My answer: $\frac{1}{48}$. I believe that it's incorrect.

Three does not divide into 16, so I cross multiplied. What am I doing wrong?

$\frac{2}{3}-\frac{1}{16}$

The intial fraction is:

$\frac{3{x}^{3}-x+4}{{x}^{3}+2{x}^{2}+6x}$

How should to make the decomposition for the denominator?

Thanks!

Is it possible to have a fraction wherein the numerator and denominator are also fractions?

For example:

$\frac{\frac{3}{5}}{\frac{7}{8}}$

I was wondering if such a situation had a name, wherein both the numerator and the denominator of a fraction consist of fractions themselves. I was also wondering if this was something common, or at least in some way useful.
