Answer:

\frac{3}{4}a-\frac{1}{2}b-3

Step-by-step explanation:

Given the expressions: 4 -\frac{2}{3}b+\frac{1}{4}a $  and $ \frac{1}{2}a + \frac{1}{6}b - 7.

We add:

4 -\frac{2}{3}b+\frac{1}{4}a + \frac{1}{2}a + \frac{1}{6}b - 7\\\\$First, we reorder the terms$\\\\=4  - 7-\frac{2}{3}b+ \frac{1}{6}b+\frac{1}{4}a + \frac{1}{2}a \\\\=-3+(\frac{1}{6}-\frac{2}{3})b+(\frac{1}{4}+\frac{1}{2})a\\\\=-3-\frac{1}{2}b+\frac{3}{4}a\\\\=\frac{3}{4}a-\frac{1}{2}b-3
