To solve the expression \( \frac{4}{5} - 0.75 \), we need to express both terms with a common denominator.

1. Convert 0.75 into a fraction:
\[
0.75 = \frac{75}{100} = \frac{3}{4}
\]

2. Find a common denominator for \( \frac{4}{5} \) and \( \frac{3}{4} \). The least common denominator (LCD) between 5 and 4 is 20.

- Convert \( \frac{4}{5} \) to have a denominator of 20:
\[
\frac{4}{5} = \frac{16}{20}
\]

- Convert \( \frac{3}{4} \) to have a denominator of 20:
\[
\frac{3}{4} = \frac{15}{20}
\]

3. Subtract the two fractions:
\[
\frac{16}{20} - \frac{15}{20} = \frac{1}{20}
\]

Thus, \( \frac{4}{5} - 0.75 = \frac{1}{20} \).
