It seems like you're trying to perform an arithmetic operation. Let's break it down:

You have the expression:

\[
\frac{4}{5} - \frac{3}{4} \times \frac{3}{10}
\]

We follow the order of operations (multiplication before subtraction). First, calculate the multiplication part:

\[
\frac{3}{4} \times \frac{3}{10} = \frac{9}{40}
\]

Now, we subtract this result from \(\frac{4}{5}\). To do this, we need a common denominator for \(\frac{4}{5}\) and \(\frac{9}{40}\).

The least common denominator (LCD) of 5 and 40 is 40. Rewriting \(\frac{4}{5}\) as \(\frac{32}{40}\), we can now subtract:

\[
\frac{32}{40} - \frac{9}{40} = \frac{23}{40}
\]

Thus, the result of the expression is:

\[
\frac{23}{40}
\]
