To find the sum of fractions, you need to have a common denominator. In this case, the common denominator of 4 and 9 is 36.

First, we need to convert both fractions to have a denominator of 36. To do this, we multiply both the numerator and denominator of the first fraction, 3/4, by 9. We get (3 * 9) / (4 * 9) = 27/36.

For the second fraction, 1/9, we need to multiply both the numerator and denominator by 4. We get (1 * 4) / (9 * 4) = 4/36.

Now that both fractions have the same denominator of 36, we can add them together: 27/36 + 4/36.

To add fractions with the same denominator, we simply add their numerators and keep the denominator the same.

Therefore, we have 27/36 + 4/36 = 31/36.

So, the sum of 3/4 + 1/9 is 31/36.
