Evaluate the expression shown below and write your answer **as a fraction** in simplest form.

start fraction, 15, divided by, 16, end fraction, minus, start fraction, 1, divided by, 20, end fraction

1615​−201​

To evaluate the expression \(\frac{15}{16} - \frac{1}{20}\), follow these steps:

1. **Find a common denominator**:  
   The least common denominator (LCD) of 16 and 20 is 80.

2. **Convert each fraction to have the LCD**:
   \[
   \frac{15}{16} = \frac{15 \times 5}{16 \times 5} = \frac{75}{80}
   \]
   \[
   \frac{1}{20} = \frac{1 \times 4}{20 \times 4} = \frac{4}{80}
   \]

3. **Subtract the fractions**:
   \[
   \frac{75}{80} - \frac{4}{80} = \frac{75 - 4}{80} = \frac{71}{80}
   \]

The answer is \(\frac{71}{80}\).
