To add the fractions $\frac{7}{16} + \frac{7}{20}$, we need to follow these steps:

Step 1: Find a common denominator

The denominators are 16 and 20. The least common denominator (LCD) of 16 and 20 is 80. We will convert both fractions to have a denominator of 80.

$\frac{7}{16} = \frac{7 \times 5}{16 \times 5} = \frac{35}{80}$ $\frac{7}{20} = \frac{7 \times 4}{20 \times 4} = \frac{28}{80}$

Step 2: Add the numerators

Now that both fractions have the same denominator, we can add them: $\frac{35}{80} + \frac{28}{80} = \frac{35 + 28}{80} = \frac{63}{80}$

Step 3: Simplify the result (if possible)

The fraction $\frac{63}{80}$ is already in its simplest form, as 63 and 80 have no common factors other than 1.

So, the final answer is: $\frac{63}{80}$
