Some one help me pleaseee! <br> On top is the example,
Luda [366]

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
