Answer 2

Let's break down the expression step by step:

1. First, let's simplify the mixed numbers:

   • 2 1/5 = 11/5
   • 4 1/5 = 21/5
   • 2 1/9 = 19/9

2. Next, we'll perform the multiplication and addition within the parentheses:

   • (11/5 + 3.2) * (21/5 * 19/9 - 6.3)

3. Continue with the arithmetic operations:

   • (2.2) * (7.0 - 6.3)

4. Simplify further:

   • 2.2 * 0.7

5. Finally, calculate the result:

   • 1.54

So, the result of the expression (2 1/5 + 3.2) * (4 1/5 * 2 1/9 - 6.3) is approximately 1.54.
