Answer 3

To solve the expression, let's break it down step by step:

1. Simplify the expression within the parentheses: 3 - 1 8/15 = 3 - (1 + 8/15) = 3 - (15/15 + 8/15) = 3 - (23/15) = 3 - 23/15

2. Convert the whole number 3 to a fraction with a common denominator of 15: 3 = 3/1 = 45/15

3. Perform the subtraction operation: 45/15 - 23/15 = (45 - 23)/15 = 22/15

4. Now, let's simplify the expression on the right side of the division sign: 4/9 + 2/15 = (4 * 5)/(9 * 5) + 2/15 = 20/45 + 2/15

5. Convert both fractions to have a common denominator of 45: 20/45 + 2/15 = (20 * 1)/(45 * 1) + (2 * 3)/(15 * 3) = 20/45 + 6/45

6. Perform the addition operation: 20/45 + 6/45 = (20 + 6)/45 = 26/45

7. Finally, divide the expression from step 3 by the expression from step 6: (22/15) / (26/45) = (22/15) * (45/26) = (22 * 45)/(15 * 26) = 990/390 = 33/13

Therefore, the simplified result of the expression 4 - (3 - 1 8/15):4/9 + 2/15 is 33/13.
