Question 281943
2/3 + 3/4
------------
Step 1 is to get the same denominator in all fractions.
One way that always works is to multiply the the DENs given:
3*4 = 12
Use 12
Then change each fraction by multiplying NUM and DEN to get 12 in the DEN:
2/3 = 8/12
3/4 = 9/12
---------
Then you can add them
8/12 + 9/12 = (8+9)/12
= 17/12
-------
Sometimes you're asked to reduce it
--> 1 5/12
