Answer 3

To solve this expression, we'll follow the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction).

1. First, simplify within the parentheses:

   2 4/15 - (2 - 1 1/15) : 4/9 + 3/2

   2 4/15 - (1 14/15) : 4/9 + 3/2

2. Next, subtract the quantity in the parentheses:

   2 4/15 - 1 14/15 : 4/9 + 3/2

3. Now, let's perform the subtraction:

   (34/15 - 29/15) : 4/9 + 3/2

4. Simplify the subtraction in the numerator:

   (5/15) : 4/9 + 3/2

5. Simplify the fractions:

   (1/3) : 4/9 + 3/2

6. To divide by a fraction, you can multiply by its reciprocal:

   (1/3) * (9/4) + 3/2

7. Simplify the multiplication:

   3/4 + 3/2

8. To add these fractions, you need a common denominator, which is 4:

   (3/4) + (6/4)

9. Add the fractions:

   (3/4 + 6/4) = 9/4

So, the simplified result of the expression is 9/4.
