Answer 2

It seems like you have provided two mathematical expressions. Let's solve each one step-by-step:

1. $\frac{3}{2/3} - \left(-\frac{1}{5/6}\right) - \frac{2}{4/5}$

To simplify this expression, we need to take care of the negative signs first:

• The negative sign before $\frac{1}{5/6}$ becomes positive when we move it inside the parentheses.

Now, let's find the values of $\frac{2}{3}$ and $\frac{4}{5}$:

$\frac{2}{3} = 0.666666...$ $\frac{4}{5} = 0.8$

Now, we can proceed with the calculation:

$\frac{3}{2/3} = \frac{3}{0.666666...} = 4.5$

$\left(-\frac{1}{5/6}\right) = -\frac{1}{0.833333...} = -1.2$

$\frac{2}{4/5} = \frac{2}{0.8} = 2.5$

Finally, we can combine these results:

$4.5 - (-1.2) - 2.5 = 4.5 + 1.2 - 2.5 = 3.2$

So, the value of the first expression is 3.2.

2. $-0.1 + \frac{8}{1/3} - 4.4 - \left(-\frac{2}{3/4}\right)$

To simplify this expression, we need to find the values of $\frac{1}{3}$ and $\frac{3}{4}$:

$\frac{1}{3} = 0.333333...$ $\frac{3}{4} = 0.75$

Now, we can proceed with the calculation:

$\frac{8}{1/3} = 8 \times \frac{3}{1} = 24$

$-\frac{2}{3/4} = -\frac{2}{0.75} = -2.666666...$

Finally, we can combine these results:

$-0.1 + 24 - 4.4 - (-2.666666...) = -0.1 + 24 - 4.4 + 2.666666...$

Since the decimal expansion of $2.666666...$ continues indefinitely, we should round it to a finite number of decimal places for a more manageable result.

Let's round it to one decimal place:

$-0.1 + 24 - 4.4 + 2.7 = 21.2$

So, the value of the second expression is 21.2.

To summarize:

1. $\frac{3}{2/3} - \left(-\frac{1}{5/6}\right) - \frac{2}{4/5} = 3.2$
2. $-0.1 + \frac{8}{1/3} - 4.4 - \left(-\frac{2}{3/4}\right) = 21.2$
