Adding Unlike terms

When adding unlike terms you can multiply both denominators by each other numbers. By doing this you will need to multiply the numerator with the same number you multiplied the denominator with.
For example: if we have an equation that says:  12+13\frac{1}{2}+\frac{1}{3}   you will need multiply 2 by 3 and 1 by 3. Then you will multiply 1 by 2 and 3 by 2. 


Example:  1×32×3+1×23×2\frac{1\times3}{2\times3}+\frac{1\times2}{3\times2}  
Then you will just solve the problem. 
Another way is to Find the LCM or the

Least common multiple (LCM)
