That would depend on the specific problem. The "rule of three" (i.e., solving proportions) can help for many standard problems; i.e., you consider a proportion, where the percentage has a denominator of 100. Here are some examples:1) What's 17% of 2000?
The proportion to solve is: 17/100 = x/2000
2) 500 is what percentage of 2000?
The proportion to solve is: x/100 = 500/2000
3) 500 is 10% of what number?
The proportion to solve is: 500/x = 10/100
In the same way that you would solve equations because equivalent expressions are in effect equations
In problems of motion, especially involving constant acceleration, a quadratic equation will from the formulas of motion to solve for time, usually. This is just one example.
To solve problems quickly you must have simple but effective method.
Diligent study for a number of years has given me the tools I need to solve most math problems I encounter.

There is no single method. There are different methods for different problems.

There are many problems involving factors and the question needs to be more specific.

You cannot solve proper fractions. You may be able to solve problems involving fractions but that is NOT the same thing. Furthermore, the solution methods depend on the problem.
Algebra is used to solve simple problems involving know and unknown variables.
you can use it by writing out the complex into a division problem then improper fraction
