$- 1 | \frac{2}{3} - 4 | \div \frac{5}{6}$

Step 1

To divide by a fraction, multiply by its reciprocal.

$- 1 | \frac{2}{3} - 4 | \frac{6}{5}$

Step 2

To write $- 4$ as a fraction with a common denominator, multiply by $\frac{3}{3}$ .

$- 1 | \frac{2}{3} - 4 \cdot \frac{3}{3} | \frac{6}{5}$

Step 3

Combine $- 4$ and $\frac{3}{3}$ .

$- 1 | \frac{2}{3} + \frac{- 4 \cdot 3}{3} | \frac{6}{5}$

Step 4

Combine the numerators over the common denominator.

$- 1 | \frac{2 - 4 \cdot 3}{3} | \frac{6}{5}$

Step 5

Step 5.1

Multiply $- 4$ by $3$ .

$- 1 | \frac{2 - 12}{3} | \frac{6}{5}$

Step 5.2

Subtract $12$ from $2$ .

$- 1 | \frac{- 10}{3} | \frac{6}{5}$

Step 6

Move the negative in front of the fraction.

$- 1 | - \frac{10}{3} | \frac{6}{5}$

Step 7

$- \frac{10}{3}$ is approximately $- 3.\overline{3}$ which is negative so negate $- \frac{10}{3}$ and remove the absolute value

$- 1 (\frac{10}{3}) \frac{6}{5}$

Step 8

Rewrite $- 1 (\frac{10}{3})$ as $- (\frac{10}{3})$ .

$- (\frac{10}{3}) \frac{6}{5}$

Step 9
