Answer:
329/36 (9 5/36 simplified)
Explanation:
First, you convert the fractions so they both have the same denominator.
3 1/4 = 13/4 = 117 /36
5 8/9 = 53/9 = 212/36
Now that you have the same denominator, you add the numerators together but not the denominators.
117 / 36 + 212 / 36 = 329/36
Simplified, 329/36 is 9 5/36
