Answer 2

It seems like you're trying to perform a mathematical calculation. Let's break it down step by step:

1. First, simplify the fractions:

   • $3 \frac{1}{9} = \frac{28}{9}$
   • $8/9$ remains the same.

2. Next, add the fractions:

   • $\frac{28}{9} + \frac{8}{9} + \frac{8}{9} = \frac{28 + 8 + 8}{9} = \frac{44}{9}$

3. Now, calculate $0.7 \cdot 0.7$:

   • $0.7 \cdot 0.7 = 0.49$

4. Finally, perform the division:

   • $(1.6 \cdot 1.6) / \left(\frac{44}{9} + 0.49\right)$

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

• $(1.6 \cdot 1.6) / \left(\frac{44}{9} + 0.49\right) = (1.6 \cdot 1.6) \cdot \frac{9}{44 + 0.49} = \frac{2.56 \cdot 9}{44.49}$

Now, calculate the numerator:

• $2.56 \cdot 9 = 23.04$

And divide by the denominator:

• $\frac{23.04}{44.49} \approx 0.5182$ (rounded to four decimal places).

So, the result of the expression (1.6 \cdot 1.6) / \left(\frac{44}{9} + 0.7 \cdot 0.7) is approximately $0.5182$ when rounded to four decimal places.
