Answer:
The fraction would be, 8/12 and 5/12
Explanation:
To find a common denominator you need to get one of the numbers to match. In this case, 12/3 is 4. So if you did 3 x 4, you would get 12. That makes the denominator. Then you multiply the numerator by 4 too because you did it to the denominator. So 2 x 4 is 8. Making the new fraction 8/12. And since the other fraction already is at 12, you change nothing
