Answer:
3/4
Step-by-step explanation:
to add fractions you have to let them have the same denominator or bottom number
so to make 3 and 12 the same number you would multiply 3 by 4
when multiplying the bottom number of a fraction by 4 you multiply the top too
so 2/3 becomes 8/12
then you can add
1/12 + 8/12 is 9/12
at the end you can simplify 9/12 into 3/4 by dividing the equation by 3/3 or both the top and bottom by 3
