$\frac{5 a}{12} + \frac{- a}{6} + 2$

Move the negative in front of the fraction.

$\frac{5 a}{12} - \frac{a}{6} + 2$

Step 2

To write $- \frac{a}{6}$ as a fraction with a common denominator, multiply by $\frac{2}{2}$ .

$\frac{5 a}{12} - \frac{a}{6} \cdot \frac{2}{2} + 2$

Step 3

Write each expression with a common denominator of $12$ , by multiplying each by an appropriate factor of $1$ .

Multiply $\frac{a}{6}$ by $\frac{2}{2}$ .

$\frac{5 a}{12} - \frac{a \cdot 2}{6 \cdot 2} + 2$

Multiply $6$ by $2$ .

$\frac{5 a}{12} - \frac{a \cdot 2}{12} + 2$

Step 4

Combine the numerators over the common denominator.
