Answer 2

This looks like a mathematical expression that involves some operations. Let's break it down step by step:

$4 - \left(3 - \frac{1}{8/15}\right) : \left(\frac{4}{9}\right) + \left(\frac{2}{15}\right)$

First, simplify the innermost expression in the parentheses:

$4 - \left(3 - \frac{15}{8}\right) : \left(\frac{4}{9}\right) + \left(\frac{2}{15}\right)$

Now, perform the subtraction inside the parentheses:

$4 - \left(\frac{24 - 15}{8}\right) : \left(\frac{4}{9}\right) + \left(\frac{2}{15}\right)$

$4 - \left(\frac{9}{8}\right) : \left(\frac{4}{9}\right) + \left(\frac{2}{15}\right)$

Next, simplify the division:

$4 - \frac{9}{8} \times \frac{9}{4} + \frac{2}{15}$

Now, perform the multiplications:

$4 - \frac{81}{32} + \frac{2}{15}$

Combine the terms with a common denominator:

$\frac{640}{160} - \frac{81}{32} + \frac{2}{15}$

Now, find a common denominator for all terms:

$\frac{4800}{960} - \frac{3105}{960} + \frac{128}{960}$

Combine the terms:

$\frac{4800 - 3105 + 128}{960}$

Finally, simplify the numerator:

$\frac{1823}{960}$

So, the simplified result is $\frac{1823}{960}$.
