Step 2.1

To write $- 5$ as a fraction with a common denominator, multiply by $\frac{3}{3}$ .

$[\begin{array}{c} - 5 \cdot \frac{3}{3} + \frac{4}{3} & 4 + 5 \\ 2 + 2 & - 6 + \frac{1}{4} \end{array}]$

Step 2.2

Combine $- 5$ and $\frac{3}{3}$ .

$[\begin{array}{c} \frac{- 5 \cdot 3}{3} + \frac{4}{3} & 4 + 5 \\ 2 + 2 & - 6 + \frac{1}{4} \end{array}]$

Step 2.3

Combine the numerators over the common denominator.

$[\begin{array}{c} \frac{- 5 \cdot 3 + 4}{3} & 4 + 5 \\ 2 + 2 & - 6 + \frac{1}{4} \end{array}]$

Step 2.4.1

Multiply $- 5$ by $3$ .

$[\begin{array}{c} \frac{- 15 + 4}{3} & 4 + 5 \\ 2 + 2 & - 6 + \frac{1}{4} \end{array}]$

Step 2.4.2

Add $- 15$ and $4$ .

$[\begin{array}{c} \frac{- 11}{3} & 4 + 5 \\ 2 + 2 & - 6 + \frac{1}{4} \end{array}]$

Step 2.5

Move the negative in front of the fraction.

$[\begin{array}{c} - \frac{11}{3} & 4 + 5 \\ 2 + 2 & - 6 + \frac{1}{4} \end{array}]$

Step 2.6

Add $4$ and $5$ .

$[\begin{array}{c} - \frac{11}{3} & 9 \\ 2 + 2 & - 6 + \frac{1}{4} \end{array}]$

Step 2.7

Add $2$ and $2$ .

$[\begin{array}{c} - \frac{11}{3} & 9 \\ 4 & - 6 + \frac{1}{4} \end{array}]$

Step 2.8

To write $- 6$ as a fraction with a common denominator, multiply by $\frac{4}{4}$ .

$[\begin{array}{c} - \frac{11}{3} & 9 \\ 4 & - 6 \cdot \frac{4}{4} + \frac{1}{4} \end{array}]$

Step 2.9

Combine $- 6$ and $\frac{4}{4}$ .

$[\begin{array}{c} - \frac{11}{3} & 9 \\ 4 & \frac{- 6 \cdot 4}{4} + \frac{1}{4} \end{array}]$

Step 2.10

Combine the numerators over the common denominator.

$[\begin{array}{c} - \frac{11}{3} & 9 \\ 4 & \frac{- 6 \cdot 4 + 1}{4} \end{array}]$

Step 2.11

Simplify the numerator.

Step 2.11.1

Multiply $- 6$ by $4$ .

$[\begin{array}{c} - \frac{11}{3} & 9 \\ 4 & \frac{- 24 + 1}{4} \end{array}]$

Step 2.11.2

Add $- 24$ and $1$ .

$[\begin{array}{c} - \frac{11}{3} & 9 \\ 4 & \frac{- 23}{4} \end{array}]$

Step 2.12

Move the negative in front of the fraction.

$[\begin{array}{c} - \frac{11}{3} & 9 \\ 4 & - \frac{23}{4} \end{array}]$
