Answer:
11/12
Step-by-step explanation:
First you would find a common denominator between the two.
2/3 and 1/4 would be translated to 8/12 and 3/12
4 and 3 have a common denominator of 12.
In this case we multiply
4x3=12
Whatever you do to the bottem you gotta do to the top.
Since we get 2/3 and 3 is turned into 12 thats bassically 3x4=12
Do that to the top and you get 2x4=8
8/12
now with the 1/4 you would multiply it by three so it would be 3/12
8/12+3/12 =11/12
I hope I explained it well.
