Answer:
5/18
Explanation:
1/2 × 9/9 = 9/18
2/9 × 2/2 = 4/18
This means we have 9/18 and 4/18 left in the circle. Because these fractions have a common denominator, we can now subtract them from the whole to find the shaded portion:
18/18 - 9/18 - 4/18 = 5/18
The shaded portion is 5/18, which is already in simplest form.
