Explanation:

Step1: Identify the fractions to add

We have the fractions for books ($\frac{7}{20}$), music ($\frac{6}{20}$), and video games ($\frac{3}{20}$). We need to add these fractions together.

Step2: Add the numerators

Since the denominators are the same, we add the numerators: $7 + 6 + 3 = 16$. The denominator remains $20$, so we have $\frac{16}{20}$.

Step3: Simplify the fraction

We simplify $\frac{16}{20}$ by dividing both the numerator and the denominator by their greatest common divisor, which is $4$. So, $\frac{16\div4}{20\div4}=\frac{4}{5}$.

Answer:

B. 4/5
