$\frac{a - \frac{2 a - 1}{a}}{\frac{1 - a}{3 a}}$ if $a = - 1.5$

Step 1

Replace the variable $a$ with $- 1.5$ in the expression.

$\frac{(- 1.5) - \frac{2 (- 1.5) - 1}{- 1.5}}{\frac{1 - (- 1.5)}{3 (- 1.5)}}$

Step 2

Multiply the numerator by the reciprocal of the denominator.

$(- 1.5 - \frac{2 (- 1.5) - 1}{- 1.5}) \frac{3 (- 1.5)}{1 - (- 1.5)}$

Step 3

Multiply $3$ by $- 1.5$ .

$(- 1.5 - \frac{2 (- 1.5) - 1}{- 1.5}) \frac{- 4.5}{1 - (- 1.5)}$

Step 4.1

Multiply $- 1$ by $- 1.5$ .

$(- 1.5 - \frac{2 (- 1.5) - 1}{- 1.5}) \frac{- 4.5}{1 + 1.5}$

Step 4.2

Add $1$ and $1.5$ .

$(- 1.5 - \frac{2 (- 1.5) - 1}{- 1.5}) \frac{- 4.5}{2.5}$

Step 5.1.1.1

Multiply $2$ by $- 1.5$ .

$(- 1.5 - \frac{- 3 - 1}{- 1.5}) \frac{- 4.5}{2.5}$

Step 5.1.1.2

Subtract $1$ from $- 3$ .

$(- 1.5 - \frac{- 4}{- 1.5}) \frac{- 4.5}{2.5}$

Step 5.1.2

Divide $- 4$ by $- 1.5$ .

$(- 1.5 - 1 \cdot 2.\overline{6}) \frac{- 4.5}{2.5}$

Step 5.1.3

Multiply $- 1$ by $2.\overline{6}$ .

$(- 1.5 - 2.\overline{6}) \frac{- 4.5}{2.5}$
