Answer 3

To add fractions, you first need to find a common denominator. The least common multiple (LCM) of 12 and 9 is 36. Now, let's convert both fractions so they have a denominator of 36.

1/12 can be converted to a fraction with a denominator of 36 by multiplying both the numerator and denominator by 3:

1/12 = (1 * 3) / (12 * 3) = 3/36

1/9 can be converted to a fraction with a denominator of 36 by multiplying both the numerator and denominator by 4:

1/9 = (1 * 4) / (9 * 4) = 4/36

Now, we have:

1/12 + 1/9 = 3/36 + 4/36

Now that they have the same denominator, we can add them together:

1/12 + 1/9 = (3 + 4) / 36 = 7/36

So, the sum of the fractions 1/12 + 1/9 is 7/36.
