Answer:
5/9
Explanation:
When adding and subtracting fractions we need to create a common denominator. To do this we have to make the denominator the same by using the GCF and then multiplying the numerator by how much you multiplied the denominator.
1/9 + 2/3 - 2/9
1/9 + 2/3
2/3
3 * 3 = 9
2 * 3 = 6
1/9 + 6/9
Now that we have our equation set up, add the numerators together, and keep the denominator the same.
1/9 + 6/9 = 7/9
Now we can plug in our last number.
7/9 - 2/9
These numbers already have a common denominator, so we can skip the part we did last time and just go ahead and subtract these from eachother.
7/9 - 2/9 = 5/9
And that is our solution
Hope this helps :)
