Pre-Algebra Examples

$\frac{2}{3} r + \frac{1}{3} - \frac{11}{3}$

Step 1

Factor $\frac{1}{3}$ out of each term.

$\frac{1}{3} (2 r + 1 - 1 \cdot 11)$

Step 2

Multiply $- 1$ by $11$ .

$\frac{1}{3} \cdot (2 r + 1 - 11)$

Step 3

Subtract $11$ from $1$ .

$\frac{1}{3} \cdot (2 r - 10)$

Step 4

Step 4.1.1

Factor $2$ out of $2 r$ .

$\frac{1}{3} \cdot (2 (r) - 10)$

Step 4.1.2

Factor $2$ out of $- 10$ .

$\frac{1}{3} \cdot (2 r + 2 \cdot - 5)$

Step 4.1.3

Factor $2$ out of $2 r + 2 \cdot - 5$ .

$\frac{1}{3} \cdot (2 (r - 5))$

$\frac{1}{3} \cdot (2 (r - 5))$

Step 4.2

Remove unnecessary parentheses.

$\frac{1}{3} \cdot 2 (r - 5)$

$\frac{1}{3} \cdot 2 (r - 5)$

Step 5

Combine $\frac{1}{3}$ and $2$ .

$\frac{2}{3} (r - 5)$
