Answer:
17/12 or 1 5/12
Step-by-step explanation
2/3 and 3/4 is dissimilar fraction so we find some LCD or least common denominator, so 3 and 4 have no similar factors so now we multiply them 3×4= 12 so now 12 is now our least common denominator or LCD
so now we will get the numerator of the fractions 12÷3=4×2=8 and then copy the denominator 8/12 so now 2/3 = 8/12. 12÷4=3×3=9 and then copy the denominator 9/12 so now 3/4 = 9/12 and then lets add them together 8/12 + 9/12 = 17/12 and then simplify your answer using GCF or greatest common factor or divide the numerator to the denominator 17÷12 = 1.5 = 1 5/12
