Answer 2

To solve the expression $(-4,4:(-2 \frac{1}{5}) -3,2) \times \frac{5}{6}$, let's break it down step by step.

First, we'll calculate the expression within the parentheses and then multiply the result by $\frac{5}{6}$.

$(-4,4:(-2 \frac{1}{5}) -3,2)$:

First, let's convert the mixed number $-2 \frac{1}{5}$ to an improper fraction:

$-2 \frac{1}{5} = -\left(2 + \frac{1}{5}\right) = -\left(\frac{11}{5}\right)$

Now, let's substitute this into the expression:

$(-4,4:(-\frac{11}{5}) -3,2)$

Now, perform the division and subtraction inside the parentheses:

$(-4,4:\left(-\frac{11}{5}\right) - 3,2)$

$= -\left(\frac{4}{4} \times \left(-\frac{11}{5}\right)\right) - 3,2$

$= -\left(-\frac{11}{5}\right) - 3,2$

Now, let's calculate this:

$= \frac{11}{5} - 3,2$

To subtract mixed numbers, we'll first convert them to improper fractions:

$= \frac{11}{5} - \frac{16}{5}$

Now, subtract the fractions:

$= \frac{11 - 16}{5} = -\frac{5}{5} = -1$

Finally, multiply the result by $\frac{5}{6}$:

$-1 \times \frac{5}{6} = -\frac{5}{6}$
