Answer:
5/9
Explanation:
When adding or subtracting fractions, you need to make the denominators the same.
Using proportions, 1/3 is the same as 3/9 because you can multiply 1/3 by 3/3, which is equal to 1. Since 3/3 is 1, it will not affect the fraction and simply convert to 3/9.
1/3 = 3/9
Now you have this, which is simple to add.
3/9 + 2/9
This will give 5/9.
This is in lowest terms because you cannot simplify or make this fraction any smaller with whole numbers.
