You can put this solution on YOUR website! Why do you think there's a formula for everything?
Sometimes, you have to figure things out.
=============
3/4 + 1/2= ?
-------
This is simple.
1/2 = 2/4, then add
====================
Or, --> (3*2 + 4*1)/(4*2)
------------------
Don't concern yourself with formulas.

Contrary to what some might think, a formula DOES NOT exist for every math problem.
This problem is simple SIMPLIFICATION. You just need to do what has been done for many generations when ADDING fractions: Find the LCD (Lowest Common Denominator)
for all the fractions, convert any fraction that DOES NOT contain that LCD to a fraction which contains it.
Then, since the denominators will all be the same, just add the numerators and place the sum over the LCD.
That's it!!
Unless the end-result is an IMPROPER fraction, in which case you convert it to a MIXED NUMBER, if requested.
