Answer:
9/12 (equal to 3/4) and 2/12 (equal to 1/6)
9/12 + 2/12 = 11/12
Step-by-step explanation:
To get the fractions with denomonators of 12, you have to think what number you have to multiply the original denomonator by to get 12.
In the first case, 4 has to be multiplied by 3 to get 12. However, if you multiply something to the denom. then you must also multiply it to the numerator, and 3*3 = 9, which is where you get the new numerator of 9, and the new fraction of 9/12. Do the same thing to the other fraction as well.
